v0.5.2: task /view card, speed-dial toggle slots

Added

• Task detail view: /view N (or the per-row 👁 /view_N) opens a task's full detail (your verbatim
  text, a fuller read, and the steps checklist) and lets you edit its steps without starting it, on
  Telegram, Slack, and web. This brings the chat surfaces to parity with the web Kanban editor.
• Speed-dial on/off toggle slots: give a pad slot a second (OFF) command and the number becomes a
  toggle that alternates the device, kept in sync across the Telegram digit, the web pad, and the
  no-login link. Each remote-page button now washes a color fill across itself on press, which also
  acts as a brief re-tap lock so a quick double-tap can't fire twice.

Changed

• The speed-dial pad editor was decluttered, its Test button now fires the command typed in the row
  (not only the saved one), and the no-login handout page names the bot.
• The remote-control page's "Powered by Fanad" footer links to fanad.org.

Fixed

• Bare action verbs no longer hijack a task statement: "start the doc" or "done the dishes" files a
  task, while the slash form ("/done clean the garage") and a position ("start 3") still act on one.
• Renamed the web remote/link panel's CSS class (sd-share to sd-remote) so ad blockers stop
  hiding it.
• Cheat-sheet Speed Dial box no longer renders mushed together.
