Update site builder configurations and enhance migration dependencies

- Added `OptimizationConfig` to `INSTALLED_APPS` in `settings.py`.
- Updated migration dependencies in `0001_initial.py` to include `writer` for content source fields.
- Modified the `account` ForeignKey in `PageBlueprint` and `SiteBlueprint` models to use `tenant_id` for better clarity.
- Deleted obsolete implementation plan documents for phases 0-4 to streamline project documentation.
- Improved overall project structure by removing outdated files and enhancing migration clarity.
