fix(build): stop committing tsbuildinfo, wipe before tsc on docker

Root cause of the CI "Cannot find module @anydrop/shared" error:
server/tsconfig.tsbuildinfo and shared/tsconfig.tsbuildinfo were checked in.
On the Gitea runner, tsc read those files, concluded the prior (local-machine)
build was still valid, and skipped emitting shared/dist — so there was nothing
to resolve by the time server's tsc ran.

- untrack the two .tsbuildinfo files
- gitignore *.tsbuildinfo
- dockerignore **/dist, **/*.tsbuildinfo (belt-and-suspenders)
- in both Dockerfiles, delete any stray tsbuildinfo + dist dirs before tsc
