Add Campaign Animation Set editor

[robert-d-schultz]

Campaign animation sets (animations\campaign\database\bin\*.bin) previously had no real editor — only a raw XML text view. This adds a dedicated editor, plus one-click generation of a complete set from an existing battle animation set.

Editor

• Grid editor for every status and entry type (idle, selection, transitions, actions, locomotion, docks, poses, persistent metadata).
• Generate from Battle Animation Set builds a full, working set from any battle fragment. Rider and flyer variants are auto-detected (MountBin → RIDER_ slots, FLY_STAND → FLY_ slots + PERSISTENT_METADATA_FLYING), with a Force ground animations override. Locomotion clips get their root bone frozen automatically.
• Open / Save / Save As, scoped to animations\campaign\database\bin\ — the only folder this format is valid in. Save As asks for a filename only, since the generic pack-browse dialog can't navigate into a folder that has no files yet (exactly what a first save into a fresh mod pack hits).
• Generated .anim clips are held in memory until you actually save the .bin, so backing out of a generate doesn't leave orphaned files behind.
• Status names, action types and pose IDs are surfaced as known-value dropdowns with tooltips, derived from a survey of 661 vanilla cam_*.bin files.

Binary format fixes (Shared.GameFormats)

• PersistentMeta, PersistentMeta_Pose/_Dock, LocomotionEntry, TransitionEntry and UnknownEntry read their strings as (Animation, AnimationMeta, SoundMeta, Type) when the on-disk order is (Animation, Type, AnimationMeta, SoundMeta) — meta paths were landing in the wrong properties.
• PersistentMeta_Pose/_Dock had no real Weight field; it was the 4th string misread as a float.
• UnknownEntry.Value wrote an int through the float parser.
• PortholeEntry's Value0-5 are now identified and named; LocomotionEntry.Weight renamed to BlendTime to match its observed values.

Core changes worth a look

AssetEditor/Themes/Controls.xaml — DataGridCell.Foreground was set to DataGrid.CellItem.Static.Background, i.e. cell text painted the same colour as its background. Now uses ABrush.Foreground.Static, which is defined in both the Dark and Light dictionaries. This affects every DataGrid in the app.
IAnimationBinGenericFormat — added MountBin (needed for rider detection). AnimationBinWh3 is the only implementer.
EditorEnums — unchanged. The new editor reuses XML_CampaginBin_Edtior, whose only previous consumer was the removed XML bin converter.

Removed

The XML text converter for campaign .bin files (CampaignAnimBinToXmlConverter + its Validator, now CampaignAnimationSetValidator) — directly replaced by this editor. The CampaignAnimationCreator tool is untouched and still registered, although it's maybe a bit redundant.
