Fix Docker buildx COPY syntax and align package manager with Bun runtime

[Copilot]

Docker build in CI was failing due to invalid COPY command syntax and mismatched package manager commands after Bun migration.

Changes

• Fixed optional file COPY: Changed COPY logo.png ./logo.png 2>/dev/null || true to COPY logo.png* ./

  • Docker COPY doesn't support shell redirection; wildcard pattern handles optional files correctly in buildx

• Aligned package manager with runtime: Replaced yarn commands with bun equivalents

  • yarn install --frozen-lockfile → bun install --frozen-lockfile
  • yarn prisma generate → bun run prisma generate
  • yarn tsc → bun run tsc

Note: Dockerfile still references yarn.lock - Bun reads it natively without requiring bun.lockb.

# Before
COPY logo.png ./logo.png 2>/dev/null || true
RUN yarn install --frozen-lockfile

# After  
COPY logo.png* ./
RUN bun install --frozen-lockfile

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• checkpoint.prisma.io
  • Triggering command: /usr/local/bin/node /usr/local/bin/node /home/REDACTED/work/fcms-server/fcms-server/node_modules/prisma/build/child {"product":"prisma","version":"4.16.2","cli_install_type":"local","information":"","local_timestamp":"2025-12-16T07:36:48Z","project_hash":"050028f6","cli_path":"/home/REDACTED/work/fcms-server/fcms-server/node_modules/prisma/build/index.js","cli_path_hash" (dns block)
  • Triggering command: /usr/local/bin/node /usr/local/bin/node /home/REDACTED/work/fcms-server/fcms-server/node_modules/prisma/build/child {"product":"prisma","version":"4.16.2","cli_install_type":"local","information":"","local_timestamp":"2025-12-16T07:36:57Z","project_hash":"050028f6","cli_path":"/home/REDACTED/work/fcms-server/fcms-server/node_modules/.bin/prisma","cli_path_hash":"9acdd094 (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Fix all the actions ci docker image build issues and maintain the env compatibility. Don't finish until it runs on bun the actions ci pass, fix this. The ceo is really angry, and will check code quality and all. Hurry up you're the senior goat, go ahead with the pull.
Fix all the problems with the latest merge, the gh actions ci builds with docker is having problem we need to fix that.
