[PM-15847] libs/components strict migration (#15738)

This PR migrates `libs/components` to use strict TypeScript.

- Remove `@ts-strict-ignore` from each file in `libs/components` and resolved any new compilation errors
- Converted ViewChild and ContentChild decorators to use the new signal-based queries using the [Angular signal queries migration](https://angular.dev/reference/migrations/signal-queries)
  - Made view/content children `required` where appropriate, eliminating the need for additional null checking. This helped simplify the strict migration.
