Add BLE HID Host app; share the central layer via libble/
Extract the reusable BLE central/GATT client and name/value decoders into
libble/ (moved out of bt_inspector). build.sh now stages libble/*.{c,h}
into each app dir at build time and builds every app in APPS=(...).
New app ble_hid_host: connects to a BLE keyboard or mouse, discovers the
HID service (0x1812), sets protocol mode (boot when offered, else report),
subscribes to the input-report characteristics, and decodes keyboard
(modifiers + key names) and mouse (buttons + dx/dy/wheel) reports live.
Events scroll on screen and are logged with raw bytes to
apps_data/ble_hid_host/. No pairing, so encryption-gated keyboards stay
silent; open devices and most mice work. Both faps build and pass APPCHK.
