Cardano Updates

- DRep guide: fix CIP-129 rules from #683 (`type` inferred for prefixed ids, required for raw ids), keep 3 examples, and reorganize sections.

- Staking guide: add explicit prerequisite that reward withdrawal requires active DRep delegation.

- Pool operations guide: add per-operation required metadata and fix governance vote wording/section naming.

- Env vars guide: sync documented defaults with v2.1.0 values.

- Add yaci-store-admin-ui dependency to enable web-based administration
- Configure admin UI with "Cardano Rosetta Java Admin - Powered by Yaci Store" header
- Enable admin UI by default with sync controls disabled for safety
- Fix module version to inherit ${revision} from parent POM

* feat: derive HTTP status from retriable flag in error responses

Map retriable=true → HTTP 500, retriable=false → HTTP 400 instead of
returning HTTP 500 for all errors.

* fix: update behavioral tests to expect HTTP 400 for non-retriable errors

Align test assertions with refactored HTTP status code mapping where
retriable=false errors now return HTTP 400 instead of 500.

Align test assertions with refactored HTTP status code mapping where
retriable=false errors now return HTTP 400 instead of 500.

* feat: infer DRep type from CIP-129 and improve validation errors

* feat: update DRep delegation tests to infer types correctly

* fix: revert DRep error HTTP status to 500 per Rosetta specification

Replace Java-based Allure 2 CLI with Node.js-based Allure 3 (npx [email protected]) in CI workflows. Add request/response body attachments,AST-extracted assertions, and environment metadata to Allure reports. Fix pytest-env to use defaults so CLI env vars take priority.

* refactor: move e2e_tests/ into tests/e2e/

Align e2e test suite with the existing tests/ directory structure.

- Rename Python package: e2e_tests -> e2e (all imports updated)
- Remove redundant example.env (superseded by .env.example)
- Remove requirements.txt (superseded by pyproject.toml + uv.lock)
- Update README quick start to use uv sync
- Fix pytest.ini inline comment breaking pytest-asyncio config
- Update docs GitHub link to new path

* test(e2e): add preview network support and uv packaging

- Add pyproject.toml with uv dependency management
- Add .env.example with all configuration options documented
- Add prepare_wallet.py for wallet setup and on-chain lookups
- Gitignore private .*.env files

* chore(e2e): fix ruff lint warnings

- Replace bare except with except Exception
- Remove unused imports (auto-fixed by ruff --fix)
- Remove unused local variables
- Add rich to pyproject.toml dependencies

* fix(e2e): on-chain validation in prepare_wallet.py

- Fix blockfrost_get() missing /v0 in URL path (was redirecting to HTML)
- Fix DRep lookup to use bech32 encoding (Blockfrost rejects hex format)
- Add on-chain checks: stake key registration state, pool retirement epoch, DRep active/expired status, proposal open/closed status
- Merge status + validate into single 'check' command with UTXO table
- Add pool retirement epoch awareness (retiring vs actually retired)
- Add help command, lookup finds fresh active DReps and open proposals

Add behavioral tests and golden examples for dRepVoteDelegation and
poolGovernanceVote operations in data endpoints (/block, /search/transactions,
/network/options).

- 13 behavioral tests validating metadata structure for all 4 drep.type
  variants (key_hash, script_hash, abstain, no_confidence) and pool vote
  variants (yes, no), plus multi-vote-per-tx validation
- 5 data golden examples: 2 block, 2 search, 1 network/options
- Add governance test data (blocks + tx hashes) to network_test_data.yaml
- Fix pytest.ini env vars to use D: prefix so CLI overrides work
