[Client] - Migrate to Signal-based Input/Output/Queries

[Char2sGu]

Desired Changes

The new signal-based input/output/query API enables full reactivity in components, and also assists the migration to OnPush change detection, since signal changes will always trigger view updates.

This migration can be automated by ngxtension's migration schematics:

• https://ngxtension.netlify.app/utilities/migrations/signal-inputs-migration/
• https://ngxtension.netlify.app/utilities/migrations/new-outputs-migration/
• https://ngxtension.netlify.app/utilities/migrations/queries-migration/

This migration would involves a great amount of changes and would likely be time-consuming.
