Add report logos and configurable folder scan depth

Report branding (top-left MSP logo, top-right client logo):
- Add MspLogo to AppSettings; client logo already on TenantProfile
- IUserSessionService.CurrentBranding composes MSP + active profile logo
- New reusable LogoUpload component (InputFile -> base64 LogoData, 512KB cap)
- MSP logo upload in Settings; optional client logo in profile create/edit
- Wire ReportBranding into all 6 HTML export pages
- Fix EditProfile dropping ClientLogo on edit

Storage metrics: expose folder scan depth (0-20) in scan options UI,
passed to existing StorageScanOptions.FolderDepth recursion.
