A very large number of improvements in the too-long-neglected and incomplete mobile version of the site:

- support inventory tags (display in listing, on card page, filtering, add Tools->Manage Tags)
- add support for card grouping in decks same as desktop version (by type/color/tag/none)
- add "Add to Deck & Inventory" and "Add from Inventory" modes to decklists
- add support in decks for properly showing the card details and if they're inventory linked
- fixes for forum styling on narrower mobile screens
- add support for creating/renaming/deleting decks and folders
- fixed card links in decks & inv to properly show exact printing image on card page straight away, not just "default image"
- add filtering support to huge 'select listings' - like the edition selector
- many small fixes, architectural cleanups, dependency updates

- imported a bunch of missing SLD cards
- imported 5 new WPN 2026 promos
- imported the 5 new Year of the Horse 2026 promos
- imported 2026 Magicfest Wayfarer's Bauble
- imported Avatar: the Last Airbender Eternal Art Series
- imported 3 missing promos for 2026 Store Champs, in "WPN/Gateweay" edition

still missing the Art Series for the last 2 expansions, I hope to address this tomorrow, together with double-sided tokens for TMNT
