gat562_30s_mesh_kit has an always-on external PA rated at +30dBm, but the firmware wrote tx_power_dbm straight to the SX1262 register (capped at 22), so the app/CLI/UI never matched the real radiated power and couldn't ask for more than 22 even though the hardware supports it. Add a generic, macro-gated PA gain-curve resolution in RadioLibWrapper::setTxPower() (the single choke point every TX-power path already funnels through), reusable by any future board with a similar PA. For this board, reuse the vendor-measured 869MHz curve from the open upstream Meshtastic PR that added it for the same physical module (meshtastic/firmware#11212): pick the lowest SX1262 setting whose measured output reaches the requested dBm, clamped at the PA's saturation knee. Bump LORA_TX_POWER/MAX_LORA_TX_POWER to 30 for this variant only -- the other three GAT562 boards use the SX1262's own PA_BOOST (22dBm, no external PA) and are unaffected. Since a request below the PA's floor gain (14dBm) still radiates at that floor, also make CommonCLICallbacks::setTxPower() return what was actually applied, and have every setter (BLE CMD_SET_RADIO_TX_POWER, CLI "tx", simple_repeater/room_server/sensor) persist and report that value instead of the raw request -- so tx_power_dbm never silently disagrees with the physical output in either direction.
