release: order book and longer fund-flow analysis

[moscowchill]

Release PR #203. Replaces game-themed market UI with a standard order book and adds 7-day and 30-day analysis, with explicit partial-history and taker-volume labels. The release tree is identical to qualified source f49dcd0. Local validation: 654 unit tests, 45 production-build browser scenarios, lint, TypeScript, formatting, API drift, Go tests/race tests/vet/build. All feature-PR CI jobs passed. Paired frontend/API rollout after read-only canary acceptance. No database migration, retention/index change, or historical backfill. Prior release is retained for rollback.

Release review complete: main-to-dev diff contains exactly the reviewed 23 files from #203, and the release tree matches qualified source f49dcd0. All three release CI jobs passed. Local gates include 654 unit tests and 45 production-build browser checks. Runtime scope is frontend/API only with prior artifacts retained for rollback, additive range metadata, unchanged retention/indexes, and explicit partial-history labels. Activation remains gated on read-only live-data canary checks.

Deployed and publicly verified. Browser tab and social metadata now read QRL Order Book | ZondScan; Arena and game UI are removed. Live 7-day and 30-day endpoints passed range and volume arithmetic checks. Phone/desktop checks passed in both themes with no overflow or JavaScript errors, loaded fonts, and exact served asset hashes. The 30-day view correctly labels partial retained history. Local qualification passed 654 unit tests, 45 browser checks, Go tests/race/vet/build and both PR CI runs. Startup configuration is saved, prior release recovery is retained, temporary test services are stopped, and merged feature branches are cleaned up. No node/database migration or retention change was part of this release.
