feat(crash): hand off reports by email instead of the Gitea issue tracker

Filing a Gitea issue requires an account on the instance, so anonymous
reporters hit a login wall — Gitea has no anonymous issue creation. Switch
both the crash-report and manual problem-report paths to compose a
pre-addressed email via ACTION_SENDTO (mailto:), which needs no account and
preserves the existing no-INTERNET, user-sends-it-themselves model. The full
report rides in EXTRA_TEXT, so the old URL-length cap and clipboard-paste
fallback are gone (clipboard copy stays as a safety net).
