Add local override for locks TTLock never reports an auto-lock delay for

[jbergler]

Summary

Some locks never return autoLockTime from TTLock's /lock/detail API at all (locks missing featureValue bit 4 - "support configuration of auto lock time"). Without that field, the coordinator has no way to guess when the lock has auto-relocked, so the lock entity sits shown as "unlocked" until the next 15-minute poll happens to catch the real state (#67).

A previous suggestion in that thread - silently assume a fallback delay whenever the field is missing - was rejected by the maintainer, since TTLock's own docs say a missing field can mean either "not supported" or "just never configured," so the integration itself shouldn't infer lock behavior from an absent value.

This instead adds a new service, ttlock.set_config_override, that lets a user assert a locally-known auto-lock delay for their own lock. It's stored in the existing per-lock LockStateStore and only ever fills a gap - the real API value always wins when TTLock reports one. It drives the same auto_lock_seconds field everything else already reads (the relock-assumption logic and the AutoLock switch), so there's no separate code path to keep in sync. The existing configure_autolock service and switch (which try to configure the real lock) are untouched.

• Closes auto_lock_seconds set to -1 even though lock is relocking after 5 seconds #67

Test plan

• script/check passes (lint, type-check, full test suite - 244 tests)
• New coordinator tests cover: override fills a None API value, a real API value always wins over a stored override, setting/clearing the override applies immediately
• New service tests cover: setting the override, explicit None clearing it, an omitted field being a no-op
