refactor: clear transcription C-; T menu, move telega launcher to C-; T

The transcription menu wasn't earning its top-level keymap slot --
the commands (transcribe-audio, switch-backend, view-transcriptions,
kill-transcription) are run rarely enough that `M-x' is fine.  Drop
the `cj/transcribe-map' keymap, its `(keymap-set cj/custom-keymap
"T" ...)' binding, and the which-key labels.  Commands stay
callable by name.

That frees `C-; T' for telega, where the mnemonic actually fits.
Move the launcher from `C-; G' to `C-; T'.  Update the
which-key label, the module commentary, and the keymap-binding
test assertion.  The dashboard `g' single-letter binding stays put
-- `t' there is vterm, so dashboard letters and the global
`C-;' prefix don't share a key space anyway.
