feat(quick-260519-bs4-04): add last-refreshed header + Type/Criticality/Activity chips + broader search

- TagStatusTableWindow: new "Last refreshed: HH:MM:SS" label at top of figure;
  seeded on openWith, updated on every clean onRefreshTick_ (even when no
  rows changed, so it acts as a heartbeat).
- Three chip groups above the table (Type / Criticality / Activity),
  multi-toggle within each group, default-all-active so first-open
  shows the same 18 rows as today. Active chips use theme.Accent +
  bold, matching TagCatalogPane.applyPillStyle_.
- Broadened free-text search from Key+Name to Key+Name+Units+Labels
  (Labels are stored comma-joined in column 11). filterRows_ signature
  extended to (rows, query, activeTypes, activeCrits, activeActivities)
  with full backward compatibility on the 2-arg form via nargin defaults
  and an iscell sentinel ([] = skip, {} = exclude-all). Combined
  semantics: AND across dimensions, OR within each chip group; a chip
  group with zero active entries excludes ALL rows.
- Layout: window 520->580 px tall; five vertical strips (label, search,
  chips, table, footer); window stays resizable.
- All widgets are uicontrol 'pushbutton'/'text' so we stay inside the
  classical-figure widget family (uibutton is uifigure-only).
- onCloseRequest_ unchanged in ordering: stop+delete RefreshTimer_
  BEFORE Listeners cleanup. New handles cleared on close.
- Tests: +4 pure-logic cases (Units search, Labels search, chip AND/OR
  semantics, zero-chip-group excludes all) + 2 UI cases (label exists
  on open, label updates after tick) via new test seams
  lastRefreshedLabelForTest / tickForTest.
