fix(messages): allow full-length text on the compose/send paths too

Browse Source 
After widening the history buffers, the compose side was still the
bottleneck: the keyboard capped input at 139 bytes and the quick-message
expand buffers were 140. Raise KB_MAX_LEN to 160 (MeshCore's MAX_TEXT_LEN)
and size the expand/compose buffers to MSG_TEXT_BUF, so a message can be
typed, expanded, sent, stored and displayed at the full protocol length on
every path.

The custom-message editor now passes an explicit max bound to its 140-byte
store, so the wider keyboard buffer can't overflow it; the bot editor
already passed per-field maxima.
