Add delete_channel and keep_one_channel to the language table (after mute) and
fill all 20 language files (13 translated, English fallback for the rest), with
correct single-byte ISO-8859 accents. Wire them into the Delete Channel label,
confirmation and last-channel guard. The new strings land on empty voice-table
slots, so they play as silence (no crash, no .vpr regeneration).
flash.sh now always rebuilds the .gla language packs so edits to the language
files are actually picked up (previously a stale pack was re-flashed).

Add two codeplug primitives - codeplugAllChannelsIndexSetUnused() (frees a
channel slot: clears the in-use bitmap bit, persists the header, fixes counts)
and codeplugZoneRemoveChannelFromZoneAndSave() (removes a channel from a zone's
list) - and wire two new Channel quick-menu items:
- 'new channel': allocates the first free slot, writes a blank 145.500 FM
channel, adds it to the current zone, reloads the zone and opens Channel
Details to edit it.
- 'Delete Channel': confirmation, then scrubs the channel from every real zone
before freeing the slot. Guards against deleting the last channel and honours
the read-only/APRS lock.

Add a one-tap audio mute on the VFO and Channel screens:
- SK2 short-tap toggles mute via the built-in audioAmpMute()/audioAmpIsMuted().
The tap is only consumed by the existing "set TX TG to incoming" behaviour
while a DMR QSO is on screen, so mute works everywhere else.
- Header: a bold "M" is shown just left of the battery while muted (the
firmware's built-in strike-through over the mode text also still shows).
- LED: flashes red for 0.5s every 2s while muted (main loop), overriding the
normal RX/TX LED.
