Removes personal infra baked into copy-paste instructions and the
app's own UI ahead of an eventual public release:
- AboutModal's "Source code" link is now a build-time env var
(VITE_SOURCE_URL) instead of a hardcoded personal Gitea URL, and
hides itself when unset rather than pointing somewhere wrong
- DEPLOYMENT.md's clone steps are genericized to any git host
- LICENSE gets its previously-blank copyright/description lines filled in
- CONTRIBUTING.md adds a lightweight contributor-terms note to keep a
future dual-licensed offering possible once outside PRs start arriving
Deliberately out of scope for now: git commit history (still under the
real author identity) and the actual publish destination -- both still
undecided.
