fix(pres_mgmt): increase file upload timeout to 20 min, guard null result

- Set post_object timeout to 1200000ms (20 min) for hosted file uploads;
  the 90s default was killing large presentation file uploads
- Guard result[0] access in .then() to prevent crash when upload
  times out or is aborted (TypeError: can't access property "hosted_file_id")

-- [x] **[Files] Hide draft/flagged files from list** — `hide_draft` prop in `launcher_file_cont.svelte`
-  now hides files with `file_purpose == 'outline'`, `'draft'`, or `'admin'` when the launcher's
-  hide-draft toggle is enabled. (2026-04-19)
+- [x] **[Files] Hide internal-purpose files from Launcher by default** — renamed `hide_draft` prop
+  to `show_internal_purpose_files` in `launcher_file_cont.svelte`; logic flipped so `false` (the
+  default) hides files with `file_purpose == 'outline'`, `'draft'`, or `'admin'`. Store key renamed
+  from `hide_content__draft_files` (inverted, misleading) to `show_content__internal_files: false`
+  (show-on-opt-in, consistent with all other `show_content__*` flags). Updated across all 8 Launcher
+  templates that pass this prop. (2026-04-19, revised 2026-04-20)

+- [x] **[Launcher] Remove duplicate session API call on session select** — `menu_session_list.svelte`
+  was calling `load_ae_obj_id__event_session` directly AND then `goto()` triggered `+page.ts` which
+  also called it — two concurrent calls per session click. Removed the direct call entirely;
+  `+page.ts` is now the sole owner of session data loading. `goto()` promise assigned to
+  `ae_promises.slct__event_session_id` to drive the existing `{#await}` spinner. (2026-04-20)
