show__session_li_poc_field was local-browser-only and the session list
prop computation ignored the admin's hide__session_poc master switch
entirely, so disabling POC for an event didn't hide the column if a
user's browser had it toggled on.
- Add show__session_li_poc_field to PressMgmtRemoteCfg + Config page UI
(Session Field Visibility) + sync_config__event_pres_mgmt() lock-synced
block, so it's admin-configurable per event like the other display flags
- Fix list/table column visibility to hide__session_poc || !show__session_li_poc_field
in pres_mgmt/+page.svelte and locations/ae_comp__event_location_obj_li.svelte
- Remove the now-redundant local "Show/Hide POC Column" toggle buttons from
ae_comp__events_menu_opts.svelte and event_page_menu.svelte
- Log the fix in PROJECT__AE_Events_PressMgmt_Config_Cleanup.md
