Delete URL redirection for legacy eventyay-xx websites

[hongquan]

Those URLs are for logged-in users, not for public search. We don't need to keep them alive.

Reviewer's Guide

Removes legacy eventyay-xx URL redirections and associated helper code, simplifying the main domain URL configuration so legacy paths no longer resolve for logged-in users or public access.

File-Level Changes

Change	Details	Files
Remove legacy URL redirect support for old event/talk/video routes.	Deleted EXCLUDED_LEGACY_PREFIXES and MATCHED_LEGACY_SUBPATHS constants and their derived regex helper variables used to detect legacy paths. Removed legacy_redirect_patterns definitions, including routes for /video assets, /video SPA index, /video/<event_identifier> redirects, and generic legacy event/talk redirects based on event slugs. Updated urlpatterns composition to no longer include legacy_redirect_patterns, keeping only common, storage, plugin, presale, and unified event patterns in order.	app/eventyay/multidomain/maindomain_urlconf.py app/eventyay/multidomain/redirects.py

Hey there - I've reviewed your changes - here's some feedback:

• Since the legacy_redirect_patterns and redirects module are removed, double-check maindomain_urlconf.py for any remaining unused imports or helpers that were only referenced from those patterns and clean them up to keep the URL config minimal.
• Now that legacy URL names like video.legacy.* and talk.legacy.* are gone, search for any references to those URL names (e.g., in templates or redirects) and remove or update them to avoid runtime reverse resolution errors.
