Skyler Lehmkuhl 2cbaf67583 Raster keyframe timeline UI: display + explicit creation + no lazy create
Make raster layers behave like vector on the timeline.

- Timeline: draw a diamond per `RasterKeyframe` (mirrors the vector keyframe block).
- New Keyframe (K / menu): on a raster layer, insert a BLANK cel at the playhead via
  a new undoable `AddRasterKeyframeAction` (+ `RasterLayer::insert_blank_keyframe_at`
  / `remove_keyframe`). Vector path unchanged.
- Stop lazy creation: paint tools now edit the ACTIVE keyframe (at-or-before the
  playhead) instead of creating one. The brush captures the active keyframe's exact
  time; `RasterStroke`/`RasterFillAction` resolve via `keyframe_at_mut` (error if
  none); the tool-site `ensure_keyframe_at` blocks (brush/fill/bucket/wand/quick-
  select/floating-lift) are removed — each read already bails when no keyframe exists.
  New layers still seed a keyframe at the playhead, so there's normally one to paint
  into; painting before the first keyframe is now a no-op (as intended).

Next: onion skinning.
