fix: admin action log and impersonation improvements

- Fix admin action log not displaying entries (use raw sqlite for self-join)
- Add global impersonation banner to all pages during impersonation
- Fix timestamp display in action log (convert Unix seconds to milliseconds)
- Add loginWithToken method to auth store for direct token authentication
- Fix /api/auth/me to include impersonatedBy field from JWT
- Remove duplicate impersonation code from admin page
