Spatie Media Library now uses the default FileDisk (local_private) for
new uploads instead of the public disk. Expense receipts are no longer
directly web-accessible.
- AppServiceProvider configures media-library disk from FileDisk on boot
- Change media-library fallback from 'public' to 'local'
- Expense receipt URL accessor returns authenticated route instead of
direct file URL
- Add registerMediaCollections() to Expense model
- Prevent deleting FileDisk that contains files or is a system disk
- Add media:secure command to migrate existing receipts to private disk
Fixes#187
V1/Admin -> Company (company-scoped controllers)
V1/SuperAdmin -> Admin (platform-wide admin controllers)
V1/Customer -> CustomerPortal (customer-facing portal)
V1/Installation -> Setup (installation wizard)
V1/PDF -> Pdf (consistent casing)
V1/Modules -> Modules (drop V1 prefix)
V1/Webhook -> Webhook (drop V1 prefix)
The V1 prefix served no purpose - API versioning is in the route prefix
(/api/v1/), not the controller namespace. "Admin" was misleading for
company-scoped controllers. "SuperAdmin" is now simply "Admin" for
platform administration.
