Activity log now shows human-readable change values

Field names, user names, and dates are now plain English. Faster search finds what you see.

What's New

The activity log is now much easier to read. When you track changes, you see actual names instead of IDs — user names, readable field labels, translated enum values, and local dates. The global Audit Log page has been redesigned to match the per-project tab, with improved date range filtering and search that understands the terms you're looking for.

Changes are now captured with actual old values instead of nulls, and no-op updates don't clutter the log anymore.
