Cardano Updates

feat(governance): clearer ballot voting UX (segmented vote + one entry per action)

fix(assets): stop token rows overflowing the Assets card

fix(ux): themed, non-overflowing, mobile-friendly pagination

The proposal meta row showed the governance action type as plain uppercase
text ("TREASURY WITHDRAWALS"), visually indistinguishable from the other meta
fields and hard to scan in a long list.

Add a GovernanceTypeChip that renders each Conway action type as a color-coded
outline Badge with an icon:
- treasury_withdrawals  amber   Coins
- info_action           blue    FileText
- parameter_change      purple  Settings2
- hard_fork_initiation  orange  GitBranch
- no_confidence         red     XCircle
- new_constitution      teal    FileText
- new/update_committee  indigo  Users
- unknown               slate   Hash (Title-Cased fallback label)

Used in both the mobile and desktop meta rows (single shared component, no
view drift). Purely presentational — no data or vote-flow changes.

The per-proposal voting controls were confusing: a raw OS <select> for the
Yes/No/Abstain choice, plus TWO competing actions (a green "Add to Ballot"
button in proposals.tsx AND a mystery ballot icon in VoteButton).

- Replace the native <select> with a shadcn segmented Yes/No/Abstain control
  (color-coded selected state, icons). Guard `(v) => v && setVoteKind(v)` so a
  re-click can't blank the vote read into the tx.
- One clear primary: the Vote button now states the choice ("Vote Yes",
  "Vote Yes (Proxy)") and uses the themed primary style.
- One ballot entry: the icon-only ballot button becomes a labeled "Add to
  ballot" / "In N ballots" secondary, with a tooltip distinguishing the two
  flows (vote on-chain now vs collect for co-signers).
- Remove the now-duplicate green "Add to Ballot" buttons (mobile + desktop) in
  proposals.tsx; keep the View links.

vote()/voteProxy() bodies, proxy path, keepRelevant, metadata label 674, the
closed-vote Lock state, and all toasts are unchanged.

Long token names ($drep.collective) and raw quantities pushed the value/ticker
past the card's right edge (the clipped "↗1 $S…"). Root cause: the flex row +
left group had no min-w-0, so text couldn't shrink, and the name/quantity/ticker
were never truncated.

- min-w-0 on the row + flex-1 min-w-0 on the left group (lets text shrink).
- 60px avatar wrappers flex-shrink-0 (so the image never compresses instead).
- name h3 truncates (+ title tooltip) and is bounded via truncateTokenSymbol
  for the raw-unit hex fallback; remove ml-auto from the link.
- value block flex-shrink-0; quantity via numberWithCommas (tabular-nums);
  ticker truncates with a max width + title.

Full name stays reachable via tooltip + the Cardanoscan token link.

The on-chain history rows (desktop table + mobile cards) led with the raw
truncated tx hash — the least human-meaningful field — while the actual
description ("Ballot Vote: …") was buried below. Flip the hierarchy to match
the pending-tx cards:
- primary: the dbTransaction description, or a "Sent"/"Received" fallback (and
  the cert label on desktop) so rows without a DB record aren't identified by
  a bare hash.
- date below.
- hash demoted to a quiet muted mono link with the external-link arrow.

Also standardize the hash truncation on getFirstAndLast(hash, 8, 8) (was two
different inline substring schemes) and drop the now-redundant standalone
description block on mobile. Cardanoscan links, outputs, certs, signers, and
the row actions menu are unchanged.

feat(ux): friendly-error helper + toastError wrapper

fix(mobile): keep dialogs within the viewport (responsive width + dvh + scroll)

PR 5 of the UX/mobile quick-wins pass.
- src/utils/errors.ts `getFriendlyError(error)` maps the common raw errors
  (CIP-30 {code:-2}, account-changed, 429/too-many-requests, insufficient
  funds, Blockfrost/UTXOS, user-decline) to short human messages, falling back
  to the raw message.
- src/utils/toast-error.ts `toastError(error, title?)` — destructive toast with
  the normalized message (additive; doesn't touch the TOAST_LIMIT=1 reducer).
- Adopt in DRep registration's catch (raw e.message -> getFriendlyError), while
  keeping the "Copy Error" action for raw debug details.

Other error-prone flows (new-transaction, WalletAuthModal) can adopt the
helper incrementally.

PR 4 of the UX/mobile quick-wins pass. Centered Dialogs overflowed small
screens — content (and action buttons) got clipped off-screen, especially the
wide governance modals.

Make the base DialogContent mobile-safe without changing desktop layout:
w-[calc(100%-1.5rem)] (stay within the viewport with a small margin),
max-h-[90dvh] + overflow-y-auto (scroll internally instead of off-screen). The
max-w-lg cap and centered position are unchanged at desktop. BallotModal and
RegisterDrepModal switch their max-h from vh to dvh so the mobile toolbar
doesn't hide the bottom.

(Kept dialogs centered rather than converting to a bottom sheet to avoid
restructuring positioning on the shared base that backs every dialog; the
overflow fix is the critical part. Needs a quick on-device / Chrome-MCP visual
check before promoting past preprod.)

fix(mobile): bech32-safe address inputs + decimal keypad + no iOS zoom

feat(ux): Skeleton + EmptyState primitives; fix blank pages & loading/empty bug

feat(mobile): >=44px touch targets on coarse-pointer devices

feat(mobile): viewport-fit + dvh + safe-area insets (foundations)

PR 6 of the UX/mobile quick-wins pass (input correctness).
- Recipient address fields used invalid type="string" with mobile autocorrect/
  autocapitalize active — which can silently corrupt case-sensitive bech32
  addresses. Now type="text" with inputMode="text" autoCapitalize="off"
  autoCorrect="off" spellCheck={false}.
- Amount fields get inputMode="decimal" (numeric keypad on mobile).
- Base Input uses text-base on mobile (sm:text-sm on desktop) so iOS Safari
  no longer zooms in on focus (<16px triggers it).

PR 3 of the UX/mobile quick-wins pass.
- Add shared `Skeleton` (shadcn) and `EmptyState` (Card-based) primitives.
- Wallet detail routes (info/transactions/governance/assets) rendered a blank
  fragment while `appWallet` loaded — replace with a `WalletDetailSkeleton` so
  there's no white flash on every wallet open.
- all-transactions: it showed "No transactions yet" *while still loading*
  (undefined === loading). Split into a skeleton (loading) vs an `EmptyState`
  (loaded and empty).
- proposals: plain-text "No proposals found" → `EmptyState`.

PR 2 of the UX/mobile quick-wins pass. Buttons/inputs were 32-36px, below
the recommended 44px touch target. A single @media (pointer: coarse) rule
enlarges interactive controls on touch devices only — no per-call-site
edits and zero change to desktop density. Plain text links are
intentionally excluded.

Foundational mobile fixes (PR 1 of the UX/mobile quick-wins pass):
- viewport meta gains viewport-fit=cover so env(safe-area-inset-*) resolves
  (without it the insets are always 0).
- Full-height containers use 100dvh instead of 100vh/h-screen so the layout
  isn't clipped by mobile-Safari / wallet-webview dynamic toolbars
  (_app, layout root + inner content column).
- Main header grows by the safe-area top inset on mobile so it clears the
  notch/status bar, and honors side insets in landscape.
- Mobile nav drawer offsets by the safe-area top, uses 100dvh, and pads the
  bottom for the home indicator.
- Bottom Sheet variant pads the bottom safe area.

Desktop is unchanged (insets are 0; header rule is scoped below md).
