feat(resources): multiselect on tables and knowledge, spring-loaded folders (#6721)

* feat(resources): multiselect on tables and knowledge, spring-loaded folders

Tables and Knowledge lists get the checkbox multiselect Files already had —
selection, shift-click ranges, select-all, and a shared bulk action bar for
move and delete.

Dragging a resource onto a folder row and resting there now opens that folder,
so nested filing is one gesture (macOS Finder spring-loading). Works on Files,
Tables, and Knowledge.

Selection, the action bar, the drag payload, the drag ghost, and drag teardown
are extracted to shared modules; Files migrates onto them rather than keeping
its own copies.

Bulk move and delete land as single authorized operations that take folders and
resources together, so a mixed selection commits once instead of fanning out.

Fixes two latent UI bugs: the drop-target outline referenced --accent, an
HSL-channel token only valid via hsl(), so it silently rendered as currentColor;
and rows painted hover and selected with the same surface token, making the two
states indistinguishable.

* chore(audits): re-record route ratchet after merging staging

* fix(bulk): reject a move target inside the moving subtree and report contained folders deterministically

* improvement(resources): neutral drop affordance, longer spring delay, and a body drop target

* fix(resources): drop into the open folder on Files, return on an unused spring-open, and guard bulk caps

* fix(drag): end a drag on pointer resume instead of an idle timer

* feat(resources): drag onto breadcrumbs to move back up, and round the drop ring

* fix(resources): tint the list region on drop instead of ringing it

* refactor(folders): share the spring-navigation lifecycle so Files returns too

* fix(breadcrumbs): accept a drag on the open-folder crumb too

* fix(files): keep the view in a spring-opened folder when an OS upload lands there
