Paul Trowbridge 1791bf0f0a Store stack pivot layouts in DB; drop pivot_layouts FK
pivot_layouts.source_name had a FK to sources(name) preventing stack names
from being used as layout keys. Dropped the FK so any view name works.

- database/migrate_pivot_layouts_drop_fk.sql: drop the FK constraint
- api/routes/stacks.js: add GET/POST/DELETE /:name/layouts routes
- ui/src/api.js: add getStackPivotLayouts / saveStackPivotLayout / deleteStackPivotLayout
- ui/src/pages/Pivot.jsx: use DB for stack layouts instead of localStorage;
  collapse source/stack branches into saveLayout/deleteLayout helpers
- CLAUDE.md: document pivot layout persistence pattern
