Cardano Updates

cabal's OS-prefix patch shortens unit-id prefixes (e.g.
`bytrdr-1.0.4-...` for the `byteorder` package), so parsing the
pkg-name from the uid alone misclassified lib units and failed the
post-install captured-unit check with
`slice captured 0 units for the target package 'byteorder'` even
when the captured uid WAS the right one.

Read the authoritative pkg-name from each unit's `.conf` (which
records the real package name) and fall back to uid parsing only
for bin-only units that don't have a .conf.

Adds a `deposit` field to:
- /accounts/:stake_address
- /accounts/:stake_address/registrations (per row)
- /governance/dreps/:drep_id
- /governance/dreps/:drep_id/updates (per row)

For stake registrations, falls back to epoch_param.key_deposit at the
registration's epoch when stake_registration.deposit is NULL (rows
predating db-sync's deposit column).

Requires @blockfrost/openapi 0.1.88-beta.0 for the matching schema.

fix: remove outdated Cardano light client

Add deposit field to:
- /accounts/{stake_address}
- /accounts/{stake_address}/registrations
- /governance/dreps/{drep_id}
- /governance/dreps/{drep_id}/updates

Surfaces the stake key / DRep deposit paid at registration. For
accounts endpoints, falls back to the key_deposit protocol parameter
at the registration epoch on rows that predate db-sync's
stake_registration.deposit column.
