feat: upgrade all dependencies to latest versions

Major version bumps:
- defmt 0.3 → 1.0
- esp-hal 0.22 → 1.0 (full API migration)
- esp-hal-embassy 0.5 → esp-rtos 0.2 (replacement crate)
- esp-backtrace 0.14 → 0.18
- esp-println 0.12 → 0.16
- embassy-nrf 0.2 → 0.10
- embassy-embedded-hal 0.2 → 0.6
- embassy-sync 0.6 → 0.8
- embassy-time 0.3 → 0.5
- embassy-usb 0.3 → 0.6
- embassy-usb-driver 0.1 → 0.2
- embedded-io-async 0.6 → 0.7
- heapless 0.8 → 0.9
- panic-probe 0.3 → 1.0
- minijinja 2.0 → 2.18
- owo-colors 4.0 → 4.3

embassy-executor stays at 0.9 (latest with Xtensa support via esp-rtos).
Updated ESP toolchain from 1.82 to 1.93.
