[chore](trx-rs): REUSE 3.3 compliance, drop GitHub wiki workflow

Add a root REUSE.toml annotating docs, repo metadata, logos, vendored
Leaflet (BSD-2-Clause) and the DSEG14 font (OFL-1.1) instead of
per-file headers; add LICENSES/OFL-1.1.txt. reuse lint: compliant.

Also remove .github/workflows/wiki.yml: the project moved off GitHub
to a self-hosted Gitea, so the GitHub Actions wiki-publishing workflow
no longer runs.
