Merged PR 348: #2462 - Refactor of DatabaseClient and DatabaseServer

Browse Source 
## Summary
Refactor of `DatabaseClient` and `DatabaseService` to update how connection IDs are generated. These are now provided by DatabaseService when establishing a connection.
Creation of `DatabaseClientConnection` class. This is used by `DatabaseClient` to hold a dictionary of active db connections.

## Test process
Tests have been updated to reflect the changes and all pass

- Upgraded pydantic to version 2.7.0
- Upgraded Ray to version >= 2.9
- Added ipywidgets to the dependencies
- Database Connection ID's are now created/issued by DatabaseService and not DatabaseClient
- added ability to set PrimAITE between development and production modes via PrimAITE CLI ``mode`` command
- Updated DatabaseClient so that it can now have a single native DatabaseClientConnection along with a collection of DatabaseClientConnection's.
- Implemented the uninstall functionality for DatabaseClient so that all connections are terminated at the DatabaseService.
- Added the ability for a DatabaseService to terminate a connection.
- Added active_connection to DatabaseClientConnection so that if the connection is terminated active_connection is set to False and the object can no longer be used.
- Added additional show functions to enable connection inspection.
## [Unreleased]
- Made requests fail to reach their target if the node is off
