## What
The participant preview on the simulator setup page (`admin/sports-seasons/:id/simulator`) was capped at the first 20 rows by a hard-coded `.slice(0, 20)`, so most of the field was invisible for seasons with up to ~300 participants (golf, tennis). All rows were already loaded — this was purely a UI limit.
## Changes
- **Search + pagination** — name search box (accent-insensitive via `normalizeName`) plus Prev/Next paging at 50/page, over the already-loaded rows. Page resets on filter change.
- **Sport-aware columns** — columns are derived from each simulator's `requiredInputs` + `optionalInputs` (from the manifest), labeled, with required columns marked. So F1 shows odds, NBA shows Elo, NCAA shows rating, etc.
- **Missing-input filter** — "Only show participants missing a required input" toggle (shown only when the simulator has required inputs) plus a per-row amber marker so gaps are visible at a glance.
- **Tennis/golf link-out** — for sports whose inputs live on a dedicated page (surface Elo, golf skills), a note links there instead of implying they're edited on this page.
## Notes
Column resolution is the only manifest **runtime** call, and it runs in the **loader** — this keeps the simulator manifest/registry out of the client bundle. Importing it into the client component pulled in every simulator and their transitive server-only modules (`scoring-calculator.ts → qualifying-points-discord.server`, `cs2-major-stage.ts`), which broke the Champions League setup page with a "server-only module referenced by client" error.
## Verification
`npm run typecheck`, `oxlint`, and `npm run build` (client + server) all pass with no server-only-leak error.
