fix: stop the 5 s boot wait, tell the client about a bad restore

Browse source 
NTPSettings::apply() waited up to 5 s in getLocalTime() for a clock that
can't be set before the network is up, then returned before it set TZ.
Every cold boot was 5 s slower and ran without its time zone.  It now
calls configTzTime(), which sets the zone and starts SNTP without
waiting, and save() goes through apply().  /setgeneral checked
ntpServer twice, so a request that changed only the zone was ignored.

A restore ignored the result of ShadeConfigFile::restore() and rebooted
either way, so a bad file failed with no word to the user.  The /restore
reply now validates the file and answers 400, which the restore dialog
shows, and an incomplete upload gets a 400 instead of no reply.  A
failed restore changes nothing, so loop() no longer reboots after one.
/shades.tmp, a full copy of the backup with its rolling codes, is
deleted after every restore and after /updateShadeConfig.

The 6 extra bytes in the 2026-10-18 backup: TRANS_REC_SIZE stayed 74
when noiseDetection was added to the 80-byte transceiver record, so
every backup since declares it short.  It is 80 now.  The size check
stays a warning so those backups still restore, and the sum moves to
expectedFileBytes() with tests.  The repeater record length is checked
as a warning only, since validate() also runs on shades.cfg at boot.

Commands for an unknown shade, tilt or group now log a warning, and a
socket that never pinged says so.  KNOWN_ISSUES.md is updated, including
the real cause of the ~365 ms loop stall (radio_tx busy-waits each frame
on loop()'s core).
