Update burndown e2e tests and mocks for feature flag handling

[TamasBoncz]

Summary

Fixes #109. The burndown e2e tests were failing because FF_TOKEN_REPORTING_ENABLED is off, so app.ts removes the [data-page="burndown"] nav link at runtime. The tests still tried to click that (now-missing) link, timing out for 30s × 5 tests in beforeEach.

Since burndown won't be re-enabled in the near future, this PR makes the tests skip gracefully instead of failing, and adds TODO notes so the stale assertions and incomplete mock get fixed when the flag is flipped back on.

Changes

• tests/e2e/burndown.spec.ts
  • Split the navigateToBurndown helper into bootHarness (load + wait for render) and the nav-click step.
  • In beforeEach, after the harness boots, check whether [data-page="burndown"] still exists. The flag-gating removal runs synchronously on app.js load, so the link is already gone by boot time → test.skip(...) fires before any click, avoiding the timeout.
  • Added a TODO(FF_TOKEN_REPORTING_ENABLED) block documenting the stale value assertions (old getBurndown 1500 / 248 / 2480 vs new getAiCreditBurndown 300 / 42.5 / 425).
• tests/e2e/harness.html — Added a TODO(FF_TOKEN_REPORTING_ENABLED) note on the getAiCreditBurndown mock listing the missing fields (byModel, missingPct, countedRequests, partialRequests, pendingRequests, noDataRequests, finalizableRequests, delegatedRequests, coverageByDay, daysUntilExhaustion, safeDailyBudget, projectedOverage, totalRequests) that block the status section from rendering; points to the real shape in src/core/analyzer-consumption.ts.
• src/core/constants.ts — Added a comment at the FF_TOKEN_REPORTING_ENABLED definition reminding whoever re-enables it to update the two test files above.

All three notes share the searchable tag TODO(FF_TOKEN_REPORTING_ENABLED) — a single grep surfaces every spot to fix.
