v2.0.13 — edge-to-edge fullscreen overlays, rounded-cards badge variant

- Overlays: drop the 24/40/54px inset frame on tasks, calendar,
  gallery, search, detail, edit modal, bookmarks, email, gitea and
  oumta-dashboard so they fill the viewport like the support
  overlay does. Removed the shared border-radius + overflow:hidden
  rule on their inner containers (only settings + dialog still use
  it) so the card's top colour bar isn't clipped.
- Done badge: the corner-triangle variant gets chopped by rounded
  card borders. applyDesign now toggles body.rounded-cards whenever
  --ui-radius-card > 0, and the CSS swaps the triangle for a 18px
  circle pill with the check centred. Triangle stays for square
  cards.
- Support plugin: "Close ticket" button is a regular labelled
  button now (was a 30×30 icon ghost that clipped the text). Empty
  hero state ("select a ticket") matches the board's empty style —
  centred in the column with a pixel-font blink-cursor label.
