Add Toyota PMV-C210/C215 TPMS support

[xeonvs]

Hey! This adds working Toyota PMV-C210 / PMV-C215 support and cleans up the receiver path around it.

The Toyota decoder is split into a small platform-independent core and a thin Flipper adapter. It uses an async FSK preset at 433.92 MHz, validates the frame CRC, and reports the sensor ID, pressure, temperature, and status.

There are a few receiver improvements included as well:

• repeated packets update the existing sensor and move it to the top of the list
• Toyota rows show the full 8-character sensor ID
• a configurable minimum RSSI filter can ignore weak/distant sensors
• the radio can be selected as Auto, Internal, or External
• the RX path now consistently uses the Sub-GHz device API
• Auto safely uses the internal radio when there is no external CC1101

I tested this in a few layers:

• built successfully with the current firmware API (88.4)
• replayed five different Toyota sensor captures and checked three invalid-frame cases
• installed and ran it on a real Flipper using the internal CC1101
• received the same live Toyota sensor repeatedly, not just a single lucky frame
• confirmed there were no external-radio initialization errors on hardware without an external CC1101

The explicit External option is implemented through the same device API, but I could only hardware-test the internal radio because I do not currently have an external CC1101 module.

Closes #7

Related to #22 and #24 because this also refreshes the app for the current Sub-GHz APIs and bumps the app version to 0.3.
