fix reorg handling with hot blocks, plus ci and small devops fixes

[mooncitydev]

what changed

• processor writes: TypeormDatabase runs with supportHotBlocks: true, so the same substrate event ids can be processed again after a chain reorg. Using insert() for transfers, claims, claim creations, and extrinsics can hit duplicate key errors or leave bad rows; these are now upsert() so replays stay idempotent on the primary key (id).

• npm run build: Replaced rm -rf with npx rimraf so the build works on Windows and matches the pattern already used in commands.json.

• docker compose: The Postgres healthcheck used -U postgres while POSTGRES_USER comes from DB_USER. If someone changes the user in .env, the db never becomes healthy. The check now uses POSTGRES_USER / POSTGRES_DB inside the container.

• CI: Added a workflow that runs npm ci and npm run build on pushes and PRs to main, so TypeScript breaks are caught before merge (the existing workflow only runs when Containerfile changes).
