improvement(pinning): move pin into the context menu and make folders pinnable

- Replaces the hover-revealed inline pin button on Files, Knowledge, and Tables
  with a Pin/Unpin item in each row's right-click menu, labelled from current state
- Deletes `PinButton` and the now-unused `ResourceCell.endAdornment` slot (plus the
  `group` class `DataRow` only carried for it)
- Adds `folder` to `pinnedResourceTypeSchema` and `PINNED_RESOURCES` — no migration
  needed, `pinned_item.resource_type` is plain text — and wires Pin/Unpin into the
  Files folder rows, which sort pinned-first like every other list
- Folder pins resolve against `workspace_file_folders`, not the generic `folder`
  table: file folders are still read and written there, and `folder`'s
  `resource_type = 'file'` rows are a one-time backfill new folders never reach
