fix: derive poster session type from Dexie chain for presenter-linked files

Browse Source 
v_event_file joins event_session only via event_file.event_session_id.
Files with for_type='event_presenter' have event_session_id=NULL on the
file record itself, so event_session_type_code is structurally always NULL
from the API for these files — no amount of refreshing can fix it.

Instead of relying on the file's event_session_type_code, derive the session
type in element_manage_event_file_li_direct via the Dexie chain:
  presenter.event_presentation_id → presentation.event_session_id → session.type_code

Pass the result as context_session_type_code to element_manage_event_file_li,
which now checks EITHER the file's own event_session_type_code OR the context
prop against 'poster' to show the PDF→Image convert button.

Sessions are guaranteed in Dexie because the pres_mgmt layout loads
inc_session_li:true on every navigation.
