chore: svelte-check cleanup — fix Svelte 5 patterns in events/pres_mgmt, badges, launcher, and tests

Source changes (0 errors, 175 warnings after):
- api_post__crud_obj_v3: add backward-compat migration aliases (for_obj_type/id, obj_type/id) to nested CRUD funcs
- ae_events__event_device/presenter/session: make event_id/presentation_id optional; fall back to store value
- element_ae_obj_field_editor_v3: import type Snippet properly; mark current_value as $bindable()
- ae_comp__badge_obj_view: fix $derived(() => false) → $derived(false) for show_receipt/show_tickets
- badge templates: pass explicit event_id param to delete/update calls
- launcher/+page: capture URL params as stable consts; pass event_id to update_ae_obj__event_device
- ae_comp__event_device_obj_li: wrap setInterval in $effect; onDestroy cleanup always registered
- ae_comp__event_device_obj_li_wrapper: move console.log to $effect; fix self-closing tag
- presenter form/menu/view/list: add missing event_presentation_id to all update/delete calls
- reports/locations/presenter/+page: move store assignments into $effect + untrack; ae_acct → $derived
- session/+page: add Comp_event_presenter_form_agree import; cast for type compat
- session_view: wrap <img onclick> in <button> for accessibility/validity
- ae_comp__event_presentation_obj_li: remove unneeded event_id/session_id from create_ae_obj__event_presenter
- ae_comp__event_session_obj_li: make lq prop optional; add plain-array fallback prop
- location/+page: refactor to $derived ae_acct, $effect+untrack for stores, simplified session/file sections
- location_page_menu: add optional data prop; export interface

Tests:
- Rename ae_events__event_badge.spec.ts → ae_events__event_badge.test.ts (extended coverage)
- All test files: 'warn' → 'warning' (Playwright API), addInitScript array-destructure pattern, import type fixes
- ae_defaults: remove duplicate hide_app_cfg key; meaningful sponsorship cfg_id placeholder
- create_event_badge.spec: fix import path to use $lib alias
- event_presenter.test: fix test URL to use /presenter/:id route

NOTE: location/+page.svelte — Element_manage_event_file_li_wrap no longer receives
allow_basic/allow_moderator (now default false); file list shows but management
actions may be restricted. Follow-up needed to restore auth__kv-based access.
