add confirmation step to `CHANNEL` command (?)
context
- as of !528 (merged) users can automatically create their own channels
- however, users sometimes make typos when providing the phone numbers of admins for new channels, resulting in either (1) orphaned channels with no admins or (2) channels with random people as admins!
- so... let's (maybe) provide a confirmation dialogue to provide new admins a chance to realize and fix typos before creating a channel
behavior
WHEN a user issues CHANNEL <some valid e164 numbers>
- THEN the user will see
Are you sure you want to make the following numbers admins? <some numbers>. Response with CONFIRM CHANNEL <some numbers> if so.

open questions
- do we like this idea? ;)
