Fix company logo missing from PDFs and add AI photo save logging

When a tenant uploads a logo it is stored in Azure Blob Storage and
LogoData (the legacy DB byte[]) is cleared. All PDF controllers were
still reading the now-null LogoData, so logos never appeared on any
PDF after upload. Fixed by injecting ICompanyLogoService into all six
affected controllers (Quotes, Invoices, Deposits, GiftCertificates,
PurchaseOrders, CatalogItems) and loading the blob-stored logo first
before falling back to the legacy DB field.

Also added structured logging to the AI photo promotion path in
QuotesController Create/Edit POST so upload failures are visible in
production logs instead of silently swallowed.

Added onclick safety net to the Create and Edit quote submit buttons
so dynamically-injected hidden fields (AiPhotoTempIds) are written
before iOS Safari collects the form data on submit.
