feat: refactor analysis to use DB-driven skills (AIIA-96)

Replace hardcoded ANALYSIS_MODES lookups with database-driven skill loading:
- Add skills table to Drizzle schema with tenant-scoped, configurable skills
- Add analyses.skill_id FK and structured_result JSONB column
- Refactor runAnalysis()/runAnalysisSync() to resolve skills from DB
- Support skillId, skillSlug, or legacy mode enum (with fallback)
- Add structured data output via generateObject() + jsonSchema() for
  skills with output_type = structured_data
- Update /api/analyses POST to accept skillId/skillSlug alongside mode
- Migration 0005: creates skills table, seeds system skills, backfills
