Added adaptive coding rate support and unit tests

* Add LilyGO T-Beam 1W support
- Add board definition and variant files for ESP32-S3 based T-Beam 1W
- Add RF95_FAN_EN support to SX126xInterface for PA cooling fan
- Add SX126X_PA_RAMP_US for configurable PA ramp time (800us for 1W PA)
- Configure RF switch: DIO2 for PA, GPIO 21 for LNA control

* Set TX_GAIN_LORA to 10dB per PR feedback (offset for 1W PA)

* Apply suggestion from @Copilot

+
+            Thanks for opening your first issue. If it's helpful, an easy way
+            to get logs is the "Open Serial Monitor" button on the [Web Flasher](https://flasher.meshtastic.org).
+
+            If you have ideas for features, note that we often debate big ideas
+            in the [discussions tab](https://github.com/meshtastic/firmware/discussions/categories/ideas)
+            first. This tracker tends to be for ideas that have community
+            consensus and a clear implementation.
+
+            We're very active [on discord](https://discord.com/invite/meshtastic),
+            especially the \#firmware and \#alphanauts-testing channels. If you'll
+            be around for a while, we'd love to see you there!

+
+            We discuss work as a team in discord, please join us in the [#firmware channel](https://discord.com/invite/meshtastic).
+            There's a big backlog of patches at the moment. If you have time,
+            please help us with some code review and testing of [other PRs](https://github.com/meshtastic/firmware/pulls)!
