fix(data): reconcile symbiosis-2025 bounty amounts & names (#28)

[sacha-l]

Closes #28.

Stacked on #50 — target base is fix/plata-mia-bounties-27 while that PR is open so the diff stays clean. Once #50 merges to develop, I'll rebase this PR and retarget to develop.

Summary

• Reconciled all symbiosis-2025 bounty_prizes rows against the source-of-truth CSV added in fix(data): split Plata Mia's concatenated bountyPrize row (#27) #50.
• 9 UPDATE + 1 INSERT already applied to prod via server/scripts/reconcile-bounty-amounts-supabase.js.
• 5 SKIPs — five Marketing-track winners have no projects row at all (not just missing a bounty row). Logged in the improvement-backlog; separate follow-up issue needed with project-level metadata.
• Plata Mia was a NOOP (already correct from fix(data): split Plata Mia's concatenated bountyPrize row (#27) #50).

Files in this PR

• server/scripts/reconcile-bounty-amounts-supabase.js — new. CSV-driven general reconciliation with --dry-run, idempotent, scoped safety rules:
  • Never deletes a row. Wrong data stays visible.
  • Never auto-mutates a project with > 1 bounty rows (protects Plata Mia's shape from future cohorts).
  • SKIPs projects where expected shape is multi-row (those use the per-project Plata Mia pattern instead).
  • Supports --hackathon=<id> flag; Phase 1 only has symbiosis-2025 registered in CSV_PATHS.
• server/migration-data/prizes-symbiosis-2025.csv — two corrections to the source-of-truth from the screenshot:
  • Siphon → Siphon Protocol (DB project name), amount $500 → $1,500
  • Carbon Smart Meter amount null → $250 (legibly confirmed out-of-band)
• client/src/lib/mockWinners.ts — mirrors every prod change so Vercel preview mock mode matches prod.
• docs/improvement-backlog.md — two new entries: missing per-bounty CSVs for synergy-2025 / symmetry-2024, and the 5 missing Marketing-track projects.

Test plan

• --dry-run — showed 9 UPDATE + 1 INSERT + 5 SKIP.
• Real run — all 10 mutations applied cleanly; no errors.
• Post-fix --dry-run — 11 NOOP + 5 SKIP + 0 pending (idempotent ✓).
• Visual check on /admin WinnersTable for the 10 affected projects — human reviewer walks through once deployed. WinnersTable.tsx:547 already iterates the array; rendering is unchanged.
• Spot-check via API for 2–3 projects: e.g. GET /api/m2-program/obraclara-98b0e9 should show "bountyPrize": [{ "name": "IDEA-THON main track", "amount": 4000, ... }].

Not in scope

• synergy-2025 and symmetry-2024 reconciliation. Those events have only a Total Prize (USDC) column in payouts.csv, not per-bounty detail. Added a backlog entry asking for the same-shape spreadsheets from WebZero.
• Adding the 5 missing Marketing-track projects. They'd need project-level metadata (name, description, team wallets, categories) beyond what's in the prize CSV. Logged for follow-up.
• totalPaid[].bountyName references. The payment-history bountyName fields on ObraClara / Kleo / OpenArkiv / Chiri App / etc. still reference the old bounty names ("Kusama bounty" etc.). Payment records are a different layer — preserving the name at time-of-payment is arguably correct (audit trail). Not touched here; not logged as a concern unless fix(data): split Plata Mia's concatenated bountyPrize row (#27) #50 or ops: verify / restore fix-bounty-amounts-supabase.js (bounty amounts may not match source-of-truth CSV) #28 reviews say otherwise.
• Siphon Protocol vs Siphon rename on the projects.project_name side — the DB has "Siphon Protocol"; we updated the CSV to match. Nothing on the DB rename side.
