docs: add call graph and chain documentation to remaining methods

Add comprehensive JSDoc documentation to methods in HomeView.vue:

- latLongInAnySearchBox: Add call chain from shouldIncludeRecord
- giveDescription: Document template usage and displayAmount calls
- displayAmount: Add currency formatting chain
- currencyShortWordForCode: Document amount formatting flow
- openDialog: Document template and openGiftedPrompts usage
- openGiftedPrompts: Add dialog opening chain
- showNameThenIdDialog: Document template usage and prompt flow
- promptForShareMethod: Add sharing flow documentation

Each method now includes:
- @callGraph showing caller/callee relationships
- @chain showing complete execution paths
- @requires listing dependencies
- Enhanced parameter documentation

This completes the standardized documentation pattern across all methods,
making method relationships and dependencies explicit.
