The timeline is now the primary AI-review surface post function-
calling migration — a handful of ergonomics tweaks so scanning a
day's AI activity is less friction.
- Time-range toggle (24h / 7T / alle) right-aligned in the filter
row. Default stays `alle` so nothing changes for users who want
everything. Client-side filter — over-fetch already caps at 500.
- Each bucket shows an event-count pill next to the mission title
("8 Änderungen in dieser Iteration"), so the reader sees the
weight of an iteration before expanding.
- Revert button: slightly bigger, label reads "Rückgängig" instead
of "Revert" (matches the rest of the German UI), bold icon, hover
highlights with a softer red tuned to the theme-token palette.
No logic changes to the revert or bucketing code.
