README: document on-radio channel add/delete; fix stale dim/7-seg notes

Add a 'Managing channels on the radio' section and a feature bullet for channel
create/delete. Update the screen-dim levels (now includes 15%) and drop the
'faintly-lit inactive segments' note (inactive 7-seg segments are now off).

## Managing channels on the radio
FreeTRX can create and delete channels without a PC. Both actions live in the
**Channel quick menu** — from the Channel screen, press the **top (orange)
button** to open it, then scroll to the bottom:
- **New channel** — creates a blank **145.500 MHz FM** channel in the first free
slot, adds it to the current zone, and opens **Channel Details** so you can set
the name, frequency, tones, and so on. Press the **green** key to save. The new
channel is immediately selectable in the zone (no need to re-enter it).
- **Delete Channel** — deletes the currently-selected channel after a
confirmation (**green** confirms, **red** cancels). It is also scrubbed from
every zone that referenced it. The last remaining channel cannot be deleted,
and channels locked read-only (e.g. APRS) are protected.
> **Back up your codeplug** (via the CPS) before making bulk edits — these changes
> are written straight to the radio and there is no on-device undo.
