feat: add per-API-key weekly cost reset day/hour configuration

Allow each API key to configure its own weekly reset day (1-7, Mon-Sun)
and hour (0-23) so the relay service's weekly limit tracking can align
with upstream Claude account reset schedules instead of using a fixed
Monday 00:00 boundary for all keys.
