Fix admin page check and update database schema

- Updated the method name for checking admin pages from `is_cof_admin_page` to `is_cofld_admin_page` for consistency.
- Bumped the database version from 1.0.0 to 1.1.0 to reflect schema changes.
- Added migration functions to rename database tables and update option keys from the old `cof_` prefix to the new `cofld_` prefix during the upgrade process.
- Called the database update check in the plugin initialization hooks.
