Remove composer.lock and disable lock file generation

This commit removes composer.lock from version control and configures Composer to not generate lock files. This is appropriate for WordPress plugins where dependencies should be resolved at install time to ensure compatibility with the environment.

Changes:
- Removed composer.lock from git repository
- Added composer.lock to .gitignore
- Set "lock": false in composer.json config to prevent lock file generation
