fix: replace esbuild minify with terser to avoid 100K+ single-line JS

Production JS bundle was a few very long minified lines (first line ~105K,
max ~190K). Some JS engines/browsers (notably older Safari/iOS) fail to parse
a single minified line that long, throwing 'SyntaxError: 10' at the end of
line 1 and showing a white screen even though the asset is served complete
and valid (verified: hash matches local, node --check passes, full 564K).

Switch to terser minifier with max_line_len=120 so the bundle emits 4,988
short lines (max ~1.9K) instead of ~24 huge lines. Asset hash changes
(cache-bust). Frontend 10 tests pass; build OK.

Also fix docker-compose port: SPA is now served by nginx on :8080, so map
external 3000 -> 8080 (was 3000->3000 pointing at a removed vite dev server).
