fix(cms): gate Session hero input to upload path; warn (not error) on missing hero

Browse Source 
Edit forms (BatchEdit/TrackEdit/TrackNew) show the guidance alert instead of an
inert picker, via an AllowHeroUpload flag. Missing-hero nudge is Severity.Warning;
null-ReleaseId hero drop is now logged.

@* Session-medium fields. The hero image is resource-addressed (POST api/release/{id}/session/hero-image)
and therefore cannot be uploaded until the release exists. The file is selected here, held by the
parent form, and uploaded after the create call returns a release id — the same deferred-upload
pattern AlbumHeaderFields uses for cover art ("Will upload on submit"). The hero is optional; the
parent warns (does not block) when a Session is submitted without one. *@

@* Session-medium fields. When AllowHeroUpload is true (BatchUpload create path), the hero image
file picker is shown — the file is held by the parent and POSTed after the release is created.
When false (edit paths: BatchEdit, TrackEdit, TrackNew), the original guidance alert is rendered
instead, directing the admin to the Sessions browser per-row replace action. This gate prevents
a dead/inert control on edit forms that do not wire the hero callbacks. *@
