Surface knowledge-ingestion runs, search storylines by anchor, and seed issuers locally

[kevinhermawan]

Summary

Closes the three gaps left open when the knowledge graph shipped in #1296: the ingestion run counters had no reader, storyline search ignored the anchors, and a fresh local database had no issuers to hang anything off. Everything here was verified against a live stack with real articles rather than fixtures.

Closes #1297

Important changes

• knowledge-ingestion-runs resource at order 46. The six per-run counters plus a derived attach rate and duration, with the developments each run wrote linking back to their storylines. Development.ingestionRunId is no longer a dead end. A run that dropped sources for want of anchors now says so in its section badge.
• Storyline search reads the anchors, not just the name. Searching for what a thread is about now finds it: the term matches storyline.name or any storyline_anchor.anchor. Verified live, where "rapid" appears in no storyline name yet correctly returns two storylines.
• Trigram indexes for that search. Both columns are searched with an unanchored case-insensitive contains, which a btree index cannot serve, so every search degraded to a sequential scan as the knowledge base grew. The migration enables pg_trgm and adds GIN indexes on storyline.name and storyline_anchor.anchor.
• seed-tickers-local. The repository ships seed-data/ticker-profiles.json with 949 issuers and no loader, so a fresh database had no tickers. The script upserts by symbol, so re-running only refreshes fields.

Other changes

• Three shared list-filter definitions for the run status dropdown and the storyline filters.
• Removed a title field the run detail mapper computed that nothing rendered.

Key files to review

• apps/mediapulse/domain-api/src/resources/knowledge-ingestion-runs/dashboard-page.ts - two stat-card rows, the key-value block, and the developments table.
• packages/mediapulse/database/prisma/migrations/20260916000000_storyline_search_trigram_indexes/migration.sql - CREATE EXTENSION plus both GIN indexes, all IF NOT EXISTS.
• apps/mediapulse/domain-api/src/resources/storylines/list-filters.ts - the OR across name and anchors.
• packages/mediapulse/database/scripts/seed-tickers-local.ts - hand-rolled row validation rather than zod, which is not a dependency of that package.

How to test

1. pnpm code-quality from the repo root. 111 tasks, all green, Prettier clean.
2. docker compose up -d postgres, then pnpm --filter @mediapulse/database db:migrate:deploy.
3. pnpm --filter @mediapulse/database run seed-tickers-local and confirm 949 issuers, then run it again and confirm it is a no-op.
4. Start agent-auth-api (8080), agent-data-api (8081), agent-registry-api (8082), domain-api (8090) and Hermes (3001).
5. Open /dashboard/mediapulse/knowledge-ingestion-runs and /dashboard/mediapulse/storylines.
6. Search the storylines list for a term that appears only in an anchor and confirm the storyline comes back.

Note the agent's run route is POST /, not /run as #1296 stated.
