Update CI pipeline: enforce lint → test → build order and reduce targets

- Reorder CI jobs to run sequentially: lint, then test, then build
- Remove all unimplemented build targets, keeping only heltec_v3 and seeed_xiao_s3_wio_sx1262
- Update job dependencies with 'needs' to ensure proper execution order
