msgread fix and newmsg alert suppression when in repeater admin login page

- Bond clearing on firmware version change (lines 38-67) — stores the firmware version string in SPIFFS at /ble_ver. On boot, if it doesn't match, all stored bonds are wiped. This fixes the forget/re-pair issue after flashing. Normal reboots keep pairing intact.
- TX power -3 dBm (line 73).
Connection parameter negotiation (lines 137-147) — latency=4 for power saving when connected.
- Advertising intervals 300ms/600ms (three places) — compromise between discovery speed and power.
- No controller power-down — the header file is unchanged from stock.
