Update ir_receiver to use IRremote 4.x API

- Migrate from old IRremote 2.x API to 4.x API for consistency
- Change include from <IRremote.h> to <IRremote.hpp>
- Use IrReceiver global object instead of IRrecv class
- Update decode() method and data access patterns
- Convert rawbuf values using MICROS_PER_TICK for correct timing
- Update dump() function to use new API and IrSender naming

This fixes CI build failures by ensuring both sketches use the same
IRremote library version (4.1.2).
