fix(file-search): send legacy workspace index payloads, isolate realtime test DB, best-effort post-upload Project check

[waleedlatif1]

Summary

• Workspace file-search index jobs now use the legacy { workspaceId } payload so a rolled-back worker can still decode them; Project jobs keep { owner } (never both, which the decoder rejects). Encoding lives in fileSearchOwnerScope next to resolveFileSearchOwner
• Realtime integration setup clears inherited DATABASE_URL* / DATABASE_REPLICA_URL* / MIGRATION_DATABASE_URL and sets SIM_DB_ROLE=realtime, so a role-specific URL in the shell can't bypass the test database. Shared clearInheritedDatabaseUrls helper used by both apps
• v2 local upload PUT (object and part): after a successful write, a failing retired-Project check logs a warning and returns 204 instead of 500 (a create-only retry would otherwise hit EEXIST). The expired-session sweep cleans up the object (and completion re-authorizes the Project once Project uploads can complete); the write-failure path is unchanged

Type of Change

• Bug fix

Testing

• New route tests for both upload routes (cleanup check throws after a successful write → 204); both fail with 500 on the pre-fix routes
• dispatcher.integration.ts asserts the workspace payload carries workspaceId and no owner, and Project payloads carry owner and no workspaceId
• Ran dispatcher.test.ts and both upload route tests locally, plus biome on changed files; CI runs the full gates and integration suites

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing (new tests pass the test-audit authoring gate)
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)

Summary

This PR fixes file-search job compatibility, isolates realtime integration tests from inherited database URLs, and avoids reporting failed uploads when only a post-write Project check fails.

• Workspace jobs keep the payload shape older workers can read.
• Upload routes return 204 when the post-write Project check fails.
• Integration setups clear inherited database URLs and select the realtime role.

No actionable issues found. Tests were not run during this review.
