Michael Suchacz fbc8930fc3 fix(coderd): make chat cost summary tests deterministic (#23097)
Fixes flaky `TestChatCostSummary_UnpricedMessages` (and siblings) by
replacing implicit handler-default date windows with explicit time
windows derived from database-assigned message timestamps.

**Root cause:** Tests called `GetChatCostSummary` with empty options,
triggering the handler to use `[time.Now()-30d, time.Now())` as the
query window. The SQL filter's exclusive upper bound (`created_at <
@end_date`) can exclude freshly-inserted messages when the handler's
clock drifts even slightly past the message's `created_at`.

**Fix (test-only, `coderd/chats_test.go`):**
- `seedChatCostFixture` now captures `InsertChatMessage` return values
and exposes `EarliestCreatedAt`/`LatestCreatedAt`.
- Added `safeOptions()` helper that builds a padded ±1 min window around
DB timestamps.
- Updated 4 tests to use explicit date windows;
`TestChatCostSummary_DateRange` unchanged.

Validated with `go test -count=20` (100/100 passes).
