FOLLOW-UP: Log file deletion errors in ConfirmDelete handler

[adnaan]

Context

This follow-up task was identified during the review of PR #267.

Source PR: #267
PR Title: feat: add file upload & storage support (Roadmap 2.2)
Suggested by: @claude[bot]

Task Description

The generated ConfirmDelete handler ignores Store.Delete errors with _ = c.Store.Delete(...). While this is reasonable (the DB row is deleted regardless), a log.Printf would help operators detect orphaned files in storage.

Change in handler.go.tmpl:

// Current:
_ = c.Store.Delete(dbCtx, existing.Photo)

// Proposed:
if err := c.Store.Delete(dbCtx, existing.Photo); err != nil {
    log.Printf("warning: failed to delete file from storage: %v", err)
}

Same change needed in the Update handler's old-file cleanup path.
