Merge connectivity telematics and fuel provider platform

[roncodes]

Summary

This PR combines the committed FleetOps work from:

• Supersedes Overhaul connectivity telematics workflow #261 (feature/connectivity-telematics-overhaul)
• Supersedes Add native fuel provider integrations #262 (feature/fuel-provider-integrations)

It merges both branch histories into a new clean branch from origin/main:

• feature/connectivity-telematics-overhaul
• feature/fuel-provider-integrations

Companion fleetops-data and fleetbase.io PRs remain separate.

What Changed

• Preserves the connectivity telematics provider overhaul.
• Adds the native, extension-ready fuel provider framework with PetroApp as the built-in provider.
• Adds fuel provider connections, provider transactions, sync/import plumbing, events, API endpoints, and focused backend tests.
• Adds FleetOps UI for Connectivity > Fuel Providers and Management > Fuel Transactions.
• Keeps Connectivity sidebar order as:
  1. Telematics
  2. Fuel Providers
  3. Devices
  4. Sensors
  5. Events
• Keeps the FleetOps translation keys for:
  • menu.fuel-providers
  • menu.fuel-transactions

Verification

• PHP syntax checks passed for touched telematics and fuel-provider backend files.
• Focused ESLint passed for changed JS controllers/components/routes.
• Focused ember-template-lint passed for changed HBS templates.
• Translation YAML parse passed.
• Verified menu.fuel-providers and menu.fuel-transactions exist in every FleetOps translation file.
• npm run build passed.

Build emitted existing ember-intl missing-key warnings and existing PostCSS :is() transform warnings from shared styles, but completed successfully.
