Update docs, site generator & verification

Add and reorder BIOS path entries in the site generator (BizHawk, EmuDeck, RetroPie, RomM). Update the add-platform pipeline steps and CI workflow notes. Document verification behavior changes: FirmwareDatabase index now includes sha256; RomM uses MD5 verification (verify.py checks MD5 only); BizHawk uses SHA1; severity label for GREEN adjusted to WARNING. Clarify troubleshooting/verify output semantics (UNTESTED and mismatch reporting), add profiling fields (core_classification option and adler32), fix several path and link typos (RetroDECK path, README/CONTRIBUTING links), and other small docs polishing.
