Fixes

- PHP 8.2 deprecates dynamically declared class properties. Adding these declarations removes deprecation warnings and makes the code PHP 8.3 compatible.
- Add Elvis operator to set search string to an empty string when it's value is null to get rid of an error in the search function call.
- Imported class for OSPOS config
- Replaced private with protected in parent controller's property.
- Removed unneeded TODO
- Refactored local variables
- Replaced ternary notation
- Removed unneeded comments
- Removed unneeded class property
- Removed unneeded @property declarations
- Fixed database version
