* fix some of the things

* Addressing feedback? hmm

* Fixes

Bug 1 — Reconnect loop / Reconnect not working fixed
Bug 2 — Name-only advertising overwrites HID advertising
Bug 3 — BleHidDeviceCtx leak on re-enable
Enhancement — HID device auto-start on radio re-enable

* stuff...

* update for consistency with others

* fix crashes

and some bonus symbols

* a few symbols, i2c speed, cdn message

100kHz i2c speed seems to be more compatible with m5stack modules...and probably in general.
cdn message no longer applies

* Missed one!

* stuff
