refactor(store): move conflict detection from web handler to store layer

add SetWithVersion method with optimistic locking using atomic UPDATE query.
returns ConflictError with current state details on version mismatch.
use nanosecond timestamps for precise conflict detection in web UI.

- add ErrConflict, ConflictInfo, ConflictError types to store
- implement atomic SetWithVersion in db.go and cached.go
- migrate web handler to use SetWithVersion
- remove TOCTOU race condition from conflict detection
- fix timestamp precision bug (use UnixNano instead of Unix)
