[tickarr]: bump to v0.4.02 — fix mappings.json corruption handling, confirm Dispatcharr v0.30.0 compat

[jstevenscl]

What's new in v0.4.02

Fixed a bug where a corrupt or transiently-unreadable mappings.json would spam ERROR logs on every sweep tick forever. The plugin's internal mapping-state reader now backs up and self-heals genuinely corrupt content on first read, while a transient I/O error (file lock, permission blip, race with a concurrent writer) is logged once without touching or resetting the file — so valid mapping data can't be destroyed by a passing glitch.

Also reviewed against Dispatcharr v0.30.0's release notes (in particular the logo-assignment changes) — Tickarr assigns logos directly via the Django ORM rather than the REST upload endpoint those changes touch, so no code changes were needed for v0.30.0 compatibility.

Checklist

• Tested in my own Dispatcharr instance (live-reproduced both the corruption and transient-I/O-error paths on a test instance and confirmed correct behavior)
• Version bumped in plugin.json (0.4.01 → 0.4.02)
• source_url release asset verified reachable at the new version tag
