Fix Sentry API input validation and blacklist enum cast

[owens1127]

Summary

• Reject membership IDs above PostgreSQL BIGINT max and duration filters above INTEGER max at route validation, returning 400 instead of unhandled DB errors (Fixes API-12, API-1A, API-1K, API-1Q).
• Schema-qualify flagging."BlacklistReportSource" on admin blacklist inserts so prod Postgres finds the enum type (Fixes API-1M).

Sentry issues addressed

Issue	Error	Fix
API-12 / API-1Q	value "10000000000" is out of range for type integer	zPgInt32() on minDurationSeconds / maxDurationSeconds
API-1A	value "46116860184306851060" is out of range for type bigint	zBigIntString() capped at PG_BIGINT_MAX
API-1M	type "BlacklistReportSource" does not exist	Explicit ::flagging."BlacklistReportSource" cast in INSERT

Test plan

• bun test src/schema/input.test.ts
• bun run typecheck
• CI green
• After deploy: confirm API-12/API-1A return 400 validation errors instead of 500 for bad inputs
