feat: Remove legacy files and fix first svelte/no-at-html-tags error\n\n- Moved legacy files from src/routes/legacy to backups/legacy/src/routes/legacy.\n- Removed the empty src/routes/legacy directory.\n- Fixed a svelte/no-at-html-tags error in src/routes/idaa/(idaa)/archives/[archive_id]/+page.svelte by replacing '{@html ?.name ?? 'Archive'}' with '{?.name ?? 'Archive'}'.\n- Addressed a misidentified '{@html}' tag in src/lib/ae_core/ae_comp__hosted_files_clip_video.svelte by removing commented-out code that might have caused false positives.
