feat: Implement module-specific accent colors and enhance theme integration

This commit introduces module-specific accent colors and further integrates the primary and secondary theme colors throughout the application's UI components. Key features: - Four new customizable accent colors, one for each main module: - Empleados - Tareas - Planillas - Asistencias - These accent colors are configurable in the Settings view and persist in local storage. - Broader application of global primary and secondary colors to common UI elements like navigation bars. - Module-specific components now use their designated accent color for key visual elements (e.g., primary buttons, titles, icons, borders), providing better visual differentiation between modules. Changes include: - Extended `ui/src/stores/useUi.js` to manage state for the four new module accent colors, including actions and local storage persistence. - Added a "Module Accent Colors" section with color pickers to `ui/src/views/SettingsView.vue`. - Updated `ui/src/App.vue` to expose these module accent colors as CSS variables (e.g., `--accent-color-empleados`). - Systematically updated styles in general UI components (`ui/src/components/ui/`) and all module-specific components (`ui/src/components/{module}/` and `ui/src/views/{module}/`) to utilize the new global and module-specific theme colors. - Updated unit tests for `useUi.js` and component tests for `SettingsView.vue` to cover the new accent color functionality. A bug related to color input event handling in `SettingsView.vue` was identified and fixed during this process. This enhancement provides a more visually distinct and customizable experience across different sections of the application.

+// are done through actions. Pinia's $subscribe method is typically attached to a store instance
+// after its creation (e.g., in main.js or a plugin) to react to all state changes,
+// including direct state manipulations (if any) or changes from multiple actions.
+// For this subtask, modifying actions is a self-contained way within this file.
+// If global subscription to all state changes (even those not via these specific actions)
+// is strictly required by "subscribe method", then a Pinia plugin or setup in main.js
+// would be the more idiomatic Pinia approach. This solution prioritizes keeping logic
+// within this file and reacting to changes triggered by the defined actions.
