fix: resolve all workflow failures

- Fix const fn error: remove 'const' from rss_bytes() in metrics.rs
  (was calling non-const read_linux_rss() and unwrap_or)
- Fix formatting: run cargo fmt --all on 19 files
- Fix deny.toml: remove deprecated 'unlicensed'/'copyleft' keys,
  remove [[bans.allow]] whitelist causing all crates to be denied,
  add MPL-2.0/CDLA-Permissive-2.0/Unicode-3.0 to license allowlist,
  add advisory ignores for transitive unmaintained deps
- Upgrade wasmtime 27→42 to fix 4 CVEs (RUSTSEC-2026-0020/0021,
  RUSTSEC-2025-0046/0118); no breaking API changes
- Upgrade lru 0.12→0.16 to fix unsound IterMut advisory (RUSTSEC-2026-0002)
- Fix cargo-audit: add --ignore RUSTSEC-2023-0071 (rsa via sqlx-mysql,
  no fix available upstream)
- Fix scorecard: set publish_results: false (repo token lacks code
  scanning write access needed by 'listCommits' graphQL query)
- Add version to mycelium-browser path dep to fix wildcard ban
