Google sheets integration

This PR introduces a major feature update—Google Sheets Integration—allowing users to export and import log data directly to/from spreadsheets. It also includes significant UI modernizations and improvements to how datasets are identified and managed.

🚀 Key Feature: Google Sheets Integration

• Bidirectional Sync: Added full support for exporting processed logs to a new Google Sheet and importing them back into the tool.
• Column Mapping: Implemented a recursive JSON-path-to-column mapper that creates a clean, tabular view of complex log payloads in Sheets.
• OAuth Management: Integrated the Google Identity Services flow to securely handle spreadsheet-specific scopes.

🎨 UI Modernization & Clarity

• Accurate Terminology: Renamed "GPS Accuracy" to "Location Accuracy" throughout the app (and updated associated docs) to better reflect data coming from Wi-Fi/Cell triangulation.
• Unified Component Styles:
  • Consolidated the "Google Sheets" and "JSON" side-load buttons into a consistent green visual style.
• Clean Labels: Simplified various UI labels (e.g., "Load JSON or ZIP") to reduce visual noise.

📊 Intelligent Dataset Metadata

• Smart Filenames: Exported JSON files and GSheet titles now automatically use the earliest log date and Vehicle ID (e.g., Fleet Debugger - Vehicle_1 - 2024-05-01.json) instead of the current download time.

🧱 Core Architecture & DevOps

• Auth Centralization: Moved OAuth Client IDs and API constants into src/constants.js
• Fork-Aware Build Workflow: Updated the build-demos.yml GitHub Action to support manual triggers

Fixes #280
