site: T16 in TACTIC_NAMES_SHORT + TACTIC_ORDER + TacticGlyph (16th unique icon)

- src/App.tsx: T16 added to TACTIC_NAMES_SHORT ("Governance /
  Voting"), TACTIC_ORDER (appended after T15), and TacticGlyph
  (case n === 16 added). 16th unique SVG glyph: ballot box with
  ballot dropping in (rect for box, rect for slot, rect for
  ballot, path for the checkmark on the ballot using the accent
  fill). Uses only the path / circle / rect / polygon primitives
  matching the existing 15 glyphs.
- index.html: og:description metadata updated by the site:data
  pipeline to reflect 16 Tactics, 93 Techniques.
