Summary by Sourcery

Upgrade Angular to version 18 and update npm dependencies. Refactor ESLint configuration and SCSS files to align with new Angular and Material Design standards. Adjust event emitter names and date handling to comply with updated Angular ESLint rules. Remove unused imports and improve test maintainability.

Enhancements:

• Update Angular to version 18 and upgrade other npm dependencies.
• Refactor ESLint configuration to include new Angular and NgRx rules.
• Modify SCSS files to use updated Material Design functions and palettes.
• Refactor event emitter names in MetadataInputComponent to avoid conflicts with Angular ESLint rules.
• Update date handling in ProposalFilterComponent and DateRangeFilterComponent to use string types.

Chores:

• Remove unused NgxMatDatetimePickerModule imports and related code.
• Replace direct string usage in tests with variable references to improve maintainability.
