feat: add configurable COMMUNITY_SCRIPTS_URL for dev sourcing (#1449)

- Replace all hardcoded source URLs with $COMMUNITY_SCRIPTS_URL variable
- Default: https://git.community-scripts.org/.../ProxmoxVED/raw/branch/main
- Override: export COMMUNITY_SCRIPTS_URL=https://.../your-fork/raw/branch/xyz
- Propagates into container via build.func exports
- Updated: 43 ct scripts, 14 deferred, 22 vm scripts, 5 func files
- Document in docs/DEV_MODE.md with usage examples
- Also normalizes legacy GitHub URLs to Gitea canonical URL

misc/build.func
