Since PR #36b6d8e moved tier-installation tracking from a client-side
persistence model to a server-side derive-from-disk model, the card
display only ever updates once every file in a tier is fully on disk.
A user who picks Standard sees a blank card for the duration of the
download (often hours for large tiers like Wikibooks). Worse, if some
files finish before others, the card briefly shows a lower tier (e.g.
Essential) before promoting to the selected tier on completion, which
reads as "the system didn't accept my pick."
Backend: compute a sibling `downloadingTierSlug` by unioning installed
resource IDs with the IDs from active RunDownloadJob queue entries
(waiting + active + delayed, failed deliberately excluded), then
resolving the highest tier whose every resource is in that union. Set
only when it differs from `installedTierSlug` — no point reporting
"downloading Standard" when Standard is already fully installed.
Frontend: unify the prominent corner badge logic in CategoryCard to a
single `badgeTier` derived from selectedTier > downloadingTier >
installedTier. Spinner + "(downloading)" suffix when in flight,
checkmark for installed/selected. The pill row and lime border follow
the same source.
Verified on NOMAD3: backend correctly resolves the downloading tier
from in-flight BullMQ jobs; CategoryCard shows the spinner badge
immediately on Submit and switches to the checkmark variant when
downloads complete.

- Add installed_tiers table to persist user's tier selection per category
- Change tier selection behavior: clicking a tier now highlights it locally,
user must click "Submit" to confirm (previously clicked = immediate download)
- Remove "Recommended" badge and asterisk (*) from tier displays
- Highlight installed tier instead of recommended tier in CategoryCard
- Add "Click to choose" hint when no tier is installed
- Save installed tier when downloading from Content Explorer or Easy Setup
- Pass installed tier to modal as default selection
Database:
- New migration: create installed_tiers table (category_slug unique, tier_slug)
- New model: InstalledTier
Backend:
- ZimService.listCuratedCategories() now includes installedTierSlug
- New ZimService.saveInstalledTier() method
- New POST /api/zim/save-installed-tier endpoint
Frontend:
- TierSelectionModal: local selection state, "Close" → "Submit" button
- CategoryCard: highlight based on installedTierSlug, add "Click to choose"
- Content Explorer: save tier after download, refresh categories
- Easy Setup: save tiers on wizard completion
