Today menu features, Matrix Move trim, widget auto-advance, Wenza logo (KC-23–26)

- Today ⋯ menu: implemented the placeholder actions.
  - Background: 5 selectable themes (Default/Warm/Cool/Mono/Paper), persisted.
  - Group & Sort: group by Date (default)/Priority/Category/Quadrant and sort by
    Smart/Due/Priority/Title; non-date groupings render via UpcomingSection.
  - Select: multi-select sheet with Select All/Deselect All and bulk
    Complete/Priority/Move/Delete.
  New isolated file TodayMenuFeatures.swift; added TaskViewModel.allActiveRows.
- Matrix "Move" submenu now lists only the other three quadrants (excludes the
  current one) using clear matrix labels.
- Event Countdown (Bars) widget auto-advances: each timeline entry re-resolves
  "nearest to finish" as of its own time and refreshes at the moment the current
  event expires, so it rolls to the next event on expiry/completion.
- Splash wordmark rebranded to "wenza." (regular-weight typewriter + orange dot).
- ISSUES.md: logged KC-23 (Pick Date + time-based reminders), KC-24 (Wenza
  rebrand), KC-25 (Move trim), KC-26 (widget auto-advance).
