feat: wire in published DEF CON 34 firmware build

[thebentern]

Summary

• The DEF CON 34 build has shipped to meshtastic.github.io/event/defcon34/firmware-2.8.0.b00d76f, so populate the edition's firmware block (version/id/title/zipUrl/releaseNotes) in the bundled fallback manifest (public/data/event_firmware.json), which was null ("coming soon").
• Corrects the firmware slug from the provisional defcon2026 to the published defcon34 — utils/firmwareUrl.ts derives event/{slug}/firmware-{version} from it, so it must match the real path.
• Release notes now lead with a preview-build warning.
• Companion to feat: wire in published DEF CON 34 firmware build api#108, which makes the same change to the live API manifest.

Test plan

• Validated public/data/event_firmware.json as well-formed JSON
• Confirmed event/defcon34/firmware-2.8.0.b00d76f exists in meshtastic.github.io via the GitHub API
• Verify ?event=DEFCON shows the correct firmware version in the flasher UI

Summary by CodeRabbit

• New Features
  • Added the DEF CON 34 firmware release, including version details, download access, and release notes.
  • Included preview build guidance and updated event instructions.

A bunny hops where DEF CON shines,
With fresh firmware in tidy lines.
A preview build, a download near,
Release notes whisper, “The update’s here!”
thump thump—the flasher leaps with cheer.
