feat(tables): row-gutter drag-select, Cmd+F find, and select-all polish (#4901)

* feat(ui): allow dragging on row gutters

* feat(tables): Cmd+F find across cells + row-gutter UI polish

Find:
- New GET /api/table/[tableId]/rows/find endpoint + contract + useFindTableRows hook
- findRowMatches: case-insensitive substring search across every cell via a
  row_number() CTE + jsonb_each_text + ILIKE, returning each matching cell with
  its ordinal in the filtered/sorted view. Shared buildRowOrderBySql keeps the
  find ordinals aligned with the paginated list (with an id tiebreak).
- Cmd/Ctrl+F floating find box (search-on-Enter), cell-by-cell next/prev that
  loads the target row then reveals the cell via the existing anchor scroll.

Gutter UI:
- Row number/checkbox centered in the region left of the run button; the
  select-all header checkbox centers in the same region so they line up.
- emcn Checkbox gains an indeterminate (minus) state; select-all shows the minus
  on any partial selection and clears everything on click.

* feat(tables): inline rename from the list context menu

Wire the existing "Rename" item in the per-table context menu to inline rename
(useInlineRename + InlineRenameInput via the Resource name cell's `content`
override), matching the Files list. Enter/blur saves, Esc cancels; replaces the
prior modal.

* style(tables): restyle Cmd+F find box to match workflow search

Reuse the workflow search visual language (surface-1 panel, emcn Input, muted
"k of N" counter, size-8 ghost chevron buttons) instead of the flat custom input.
