Cards table renders at startup and on pill entry; v1.9.11

cardsRender() was mutation-only (add/import/remove/counter-sync), so
after a reload the SCP80 -> Cards table showed 'No cards defined.'
even while localStorage held presets and the SP dropdown listed them
correctly. Now:

- cardsLoad() renders the table right after rebuilding the select
- entering the Cards pill re-renders (mirrors pysim-pill pattern)

Version 1.9.10 -> 1.9.11 everywhere; SW cache otaman-v21 -> otaman-v22
