Implement code quality improvements for getLocations.ts

[Copilot]

User requested refactoring recommendations for getLocations.ts and its dependencies following best coding practices. This PR implements the code quality improvements.

Changes Implemented

• Removed commented debug code: Cleaned up lines 33-38 that contained commented-out debugging statements
• Added explicit return types: Added Promise<LocationData[]> return type to getAllLocationsFromDB and ITimeRangeInternal[] to applyTimeOverrides
• Created LocationData interface: Defined explicit interface for better type safety instead of relying on inferred types
• Extracted magic numbers into constants:
  • DAYS_BEFORE_TODAY_TO_FETCH = 1 for data retrieval window
  • MINUTES_PER_HOUR = 60 for time calculations
• Improved variable naming:
  • DB → queryUtils (more descriptive)
  • id → locationId (more specific)
  • rng → timeRange (clearer intent)
• Added comprehensive JSDoc documentation: Documented getAllLocationsFromDB with step-by-step process explanation and applyTimeOverrides with behavior clarification
• Made functions more immutable: applyTimeOverrides now creates a copy instead of mutating the input array
• Added inline comments: Clarified complex operations throughout the code
• Removed unused imports: Cleaned up unused pad import

Validation

• ✅ TypeScript compilation passes (no new type errors)
• ✅ CodeQL security scan passes (0 vulnerabilities)
• ✅ Changes maintain 100% backward compatibility

The refactoring significantly improves code maintainability, readability, and type safety without altering functionality.

Implemented code quality improvements in commit d7e7ada:

Code Clarity:

• Removed commented debug code
• Renamed variables: DB → queryUtils, id → locationId, rng → timeRange
• Extracted intermediate variables for better readability

Type Safety:

• Added explicit return type Promise<LocationData[]>
• Created LocationData interface
• Used Record<string, ...> instead of index signature

Documentation:

• Added comprehensive JSDoc for getAllLocationsFromDB explaining the 5-step process
• Added JSDoc for applyTimeOverrides clarifying override behavior

Constants:

• Extracted DAYS_BEFORE_TODAY_TO_FETCH = 1
• Extracted MINUTES_PER_HOUR = 60

Best Practices:

• Made applyTimeOverrides immutable (creates copy instead of mutating input)
• Added inline comments for complex operations
• Removed unused import (pad)
