Port API lint improvements from comet PR #5136

[Copilot]

Description

Ports vivid-planet/comet#5136 to comet-starter. Adds CI-time verification that the API NestJS AppModule can be instantiated (DI is wired correctly) and that generated files (schema.gql, block-meta.json) are up to date.

• lint:api-can-start: Runs console.ts --help with MIKRO_ORM_NO_CONNECT=true to validate AppModule + GraphQL schema generation without a database
• lint:generated-files-not-modified: Checks schema.gql, block-meta.json, and src/**/generated/* for uncommitted diffs
• lint/lint:ci: api-can-start added to parallel lint; generated-files-not-modified runs sequentially after (depends on regenerated schema)
• ormconfig.ts: Added connect: process.env.MIKRO_ORM_NO_CONNECT !== "true" to support DB-less instantiation

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:

• github.com (HTTP Only)
  • Triggering command: /usr/bin/ssh /usr/bin/ssh -o SendEnv=GIT_PROTOCOL git@github.com git-upload-pack 'vivid-planet/comet.git' (packet block)
  • Triggering command: /usr/bin/ssh /usr/bin/ssh -o SendEnv=GIT_PROTOCOL git@github.com git-upload-pack 'vivid-planet/comet.git' submodules | head -n 10 (packet block)
• iojs.org
  • Triggering command: /usr/bin/curl curl -q --fail --compressed -L -s REDACTED -o - (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)
