Add mobile reliability fixes, Bahasa Indonesia UI, and continue OCR accuracy tuning

Reliability/PoC hardening: dedupe uploads by file_hash, surface editor sync
failures instead of a false success SnackBar with a retry-without-re-OCR path,
bound the OCR pipeline fetches with timeouts, share a single ApiClient/Dio
instance app-wide, tune capture JPEG quality, and add an opt-in
docker-compose.demo.yml for a production-mode run ahead of client demos.

Translate all Flutter-side user-facing text (screens, validators, SnackBars,
the printed delivery receipt, and shared API error messages) to Bahasa
Indonesia.

Also includes in-progress OCR parser/accuracy-tuning work from the same
session: table column/unit normalization fixes, store/customer master data,
accuracy history log, and test-image renaming/cleanup.

+# Production-mode override for client demos / PoC runs.
+#
+# The base docker-compose.yml runs pfm-web-app via `npm run dev` with the source
+# directory bind-mounted in, which is what you want for daily parser.ts iteration
+# (hot reload) but is a single dev-server process - not the concurrency/latency
+# story you want in front of a client with multiple drivers uploading at once.
+#
+# This override drops the dev bind-mount (so the image's own `npm run build`
+# output isn't shadowed by live source) and runs `npm start` against that build.
+#
+# Usage:
+#   docker compose -f docker-compose.yml -f docker-compose.demo.yml up -d --build
+#
+# Rebuild before every demo run - this mode does not hot-reload code changes.
