[EPAC-1919]: Remove LiveParliamentService and live-status UI surfaces

[riddim-developer-bot]

Why

Part of the Aurora teardown (parent project: epac: Retire Aurora). The `/api/v1/live` endpoint (rate-limited 2 req/min) is being retired for cost savings. The live Parliament status feature is acceptable to remove now; re-introduction is tracked in EPAC-1928.

What changed

• Deleted `LiveParliamentService.swift` — the service that polled `/api/v1/live`
• Deleted `LiveParliamentStatus.swift` — the domain entity for the API response
• Deleted `HomeLiveCardDecision.swift` — the enum driving the live card UI branch
• Deleted `RefreshLiveParliamentStatus.swift` — the use case for polling refreshes
• Deleted `LiveParliamentServiceTests.swift` — all tests covering the removed service
• Simplified `HomeFeedView.swift`: removed the `switch liveCardDecision` block, background polling task, `refreshLiveParliamentStatus()`, `pollLiveParliamentStatus()`, and all `liveBadge*`/`liveHeadline`/`liveDetail` helpers; the live card section no longer exists
• Simplified `LoadHomeFeed.swift`: removed `LiveParliamentStatusFetching` dependency and `computeLiveCardDecision()` logic; the snapshot no longer carries live status fields
• Simplified `HomeFeedSnapshot.swift`: removed `liveParliamentStatus` and `liveCardDecision` fields
• Simplified `Ports.swift`: removed `LiveParliamentStatusFetching` protocol
• Simplified `ServicePortsAdapters.swift`: removed `LiveParliamentService: LiveParliamentStatusFetching` conformance
• Simplified `AppEnvironment.swift`: removed `debugLiveStatusFixtureIsPresent` debug flag
• Simplified `LoadHomeFeedTests.swift`: removed `MockLiveParliamentStatusFetching` and its usage from all three test cases
• Removed localization keys from `en.lproj/Localizable.strings` and `fr.lproj/Localizable.strings`: all 10 `home.live.*` keys
• Updated `docs/architecture/use-case-catalog.md`: removed iOS actor/adapters from `FetchLiveParliamentStatus` entry per catalog update rule

grep check: `grep -r -i 'live.parliament|liveParliament|LiveParliamentStatus|liveCardDecision|HomeLiveCard' ios/epac/ --include=".swift"` returns zero results.

Re-introduction of live status is tracked in EPAC-1928.

Trade-offs not taken

• Keeping the polling infrastructure for a future replacement: unnecessary complexity for a feature being retired. The rate-limiting and `/api/v1/live` backend remain; only the iOS client is cleaned up here.
• `fetchHansards(between:and:)` on `HomeFeedRepository` has no remaining call sites after this PR; left in place to avoid breaking the protocol surface — can be pruned in a separate cleanup.

Test plan

1. `cd ios && make build` — BUILD SUCCEEDED (confirmed)
2. `swiftlint --strict` on changed files — 0 violations (confirmed)
3. `LoadHomeFeedTests` — passed (confirmed)
4. `OnThisDayServiceTests` — passed (confirmed)
5. Human visual spot-check in TestFlight: confirm Home tab shows no live-status card (owner: @sunnypurewal)

Screenshots

Not applicable — live-status card is removed entirely; Home tab still renders the `todaySection` with sitting/adjourned/not-sitting status.

Resolves EPAC-1919

Release-Note: Removed live Parliament status card from Home feed (feature retirement; will return in a future update)

• Verdict: approve
• Reviewer boundary: review_only
• Acceptance criteria coverage: covered=0, missing=0, unclear=0

Summary

All acceptance criteria are met: LiveParliamentService and its full dependency chain (entity, use case, port, adapter, tests, localization keys) are cleanly deleted with zero remaining references. LoadHomeFeedTests pass after mock removal. One unrelated file in a guarded glob was swept into the PR, and one orphaned protocol method is noted but acknowledged.

Actionable findings

1. risk / follow_up — Unrelated backend debug workflow deleted in a guarded glob (.github/workflows/debug.yml)
   • .github/workflows/debug.yml is listed in the repo's guarded globs (.github/workflows/**) and is completely unrelated to the iOS live-status removal. The file is clearly a throwaway debug test (unconditional t.Fail(), inline Go source, PostgreSQL ts_headline probe) that belongs in backend/search/, not in CI. Its deletion is harmless and arguably overdue, but bundling it into a scoped iOS-only PR violates the single-reason-to-change rule and bypasses the guarded-glob review intent. File a follow-up to document why it was deleted or prune any similar stale debug workflows through a dedicated CI-hygiene PR.
   • Actionability: follow_up
2. nit / follow_up — fetchHansards(between:and:) is now a dead protocol method with no callers (ios/epac/Domain/Ports/Ports.swift)
   • The PR description correctly identifies that fetchHansards(between:and:) on HomeFeedRepository has no remaining call sites after postSittingHansard logic was removed from LoadHomeFeed. The protocol method (and its conforming implementations) is dead code. The PR chose to leave it to avoid a potentially breaking protocol surface change, which is a reasonable short-term trade-off. File a follow-up to prune the method from the protocol and all conformances before it confuses the next implementer.
   • Actionability: follow_up
