Pull request overview

This pull request migrates Angular entity list components to use Angular's new httpResource API for a more reactive and declarative approach to HTTP request management. The changes modernize the entity list loading mechanism by replacing imperative HttpClient calls with signal-based httpResource, introduce a new utility function for controlled pluralization, and update documentation to use more semantically appropriate entity name variants.

Changes:

• Introduced a new pluralize utility function with a force parameter to control pluralization behavior, allowing distinction between display names (forced plurals) and URL/file names (natural plurals)
• Migrated Angular entity list services to use httpResource with signal-based parameter management, replacing manual HttpClient subscription handling
• Refactored service architecture to use inheritance pattern with a base plural service managing list loading and a child singular service adding CRUD operations
• Updated Java template documentation to use entityNamePluralHumanized instead of entityInstancePlural for better semantic clarity
