Replace global activeSurvey$ w/component inputs

[gino-m]

Overview

This PR refactors multiple Ground components to use Angular Signals, enabling explicit data flow from MainPageComponent. This change moves away from implicit SurveyService subscriptions to a clearer, unidirectional data flow.

Changes

1. Data Flow Refactoring

• Implicit to Explicit: Transitioned from implicit ActiveSurvey service subscriptions to explicit input<Survey>() signals passed down from MainPageContainerComponent.
• MainPageContainerComponent: Now uses LoadSurvey$(id) and passes a survey signal to MainPageComponent.
• MainPageComponent: Accepts activeSurvey signal input and passes it to children.

2. Component Updates

Refactored the following components to accept activeSurvey as an input<Survey>() signal:

• DrawingToolsComponent: Updates jobs derived from activeSurvey.
• SurveyHeaderComponent: Uses activeSurvey for title.
• MapComponent: Receives activeSurvey for map data rendering.
• SidePanelComponent: Passes activeSurvey to JobListComponent.
• JobListComponent: Uses computed signal for jobs.
• SecondarySidePanelComponent: Passes activeSurvey to children.
• LoiPanelComponent: Replaces surveyId with activeSurvey().id.
• SubmissionPanelComponent: Replaces surveyId with activeSurvey().id.

3. Signal Propagation

The activeSurvey signal is now propagated down the component tree:
MainPageContainer -> MainPage -> [ Map, DrawingTools, SidePanel, SecondarySidePanel ]
SidePanel -> JobList
SecondarySidePanel -> [ LoiPanel, SubmissionPanel ]

4. Test Updates

• Updated MapComponent spec to remove SurveyService mock and use setInput.
• Created new spec files for LoiPanelComponent, SubmissionPanelComponent, and SecondarySidePanelComponent with signal-based testing patterns.
• Updated JobListComponent and DrawingToolsComponent specs.

Verification

Automated Tests

Run the test suite for the modified components:

npm test src/app/pages/main-page-container/main-page

Manual Verification

1. Navigate to a Survey: specific survey URL or select from survey list.
2. Verify Map: Ensure map loads with markers/polygons.
3. Verify Side Panel: Check if Job List loads.
4. Verify Secondary Panel: Click an LOI to see details; click a submission to see submission details.
5. Drawing Tools: Verify adding points works.

Key Design Decisions

• Signals over Observables: Migrated input properties to Signals for better reactivity and cleaner change detection.
• Explicit Dependency: Components now explicitly verify they have the required survey data via inputs rather than hidden service dependencies.
