feat(db): SQLAlchemy foundation with 24 models + JSON importer

Replaces the 12 ad-hoc JSON file stores (quality, intel, monitors,
sessions, accounts, agency, etc.) with a single SQLAlchemy-backed
database. The new foundation gives us:
  - Concurrency safety (SQLite WAL mode, file locks via SQLAlchemy)
  - Transactions (rollback on error)
  - Querying (WHERE, JOIN, ORDER BY, LIMIT)
  - Relationships (ForeignKey on monitor_id, agency_id, etc.)
  - Multi-tenant ready (everything indexed by id)

Engine:
  - Default: SQLite at $PRY_DATA_DIR/pry.db (zero-config)
  - Production: set PRY_DATABASE_URL=postgresql://... (no code change)
  - Foreign keys enabled for SQLite (off by default)

Models (24):
  quality_checks, review_items, intel_snapshots, costing_entries,
  freshness_snapshots, structure_snapshots, seo_snapshots, monitors,
  monitor_runs, accounts, browser_sessions, reports, training_datasets,
  pipelines, pipeline_runs, gdpr_requests, agencies, agency_clients,
  referral_clicks, actors, actor_runs, llm_usage, webhooks, x402_receipts

Each model maps to a former JSON store. Most have an _id field with
unique constraint so re-importing the same data is safe. The legacy
"id" and "name" fields are renamed to "<scope>_id" / "<scope>_name"
to avoid reserved LogRecord field name collisions.

JSON importer (import_json_stores):
  One-shot function that reads the existing JSON files in $PRY_DATA_DIR
  and writes them to the SQL tables. Returns a {store: count} dict.
  Idempotent: re-running with the same data is safe.

Public API:
  - get_engine()         - lazy engine creation
  - get_session()        - new Session (caller manages)
  - session_scope()      - context manager: commit/rollback
  - import_json_stores() - the one-shot importer
  - db_health()          - dict for /health endpoint
  - _has_sqlalchemy, get_db - backward-compat aliases

pyproject.toml: added sqlalchemy>=2.0.0 and aiosqlite>=0.19.0

Tests: 7/7 in tests/test_db.py pass:
  - Engine creates DB file
  - All 24 tables created
  - session_scope commits on success
  - session_scope rolls back on error
  - import_json_stores reads existing JSON
  - db_health returns dict
  - Models have unique indexes on _id columns

Test suite: 436/437 pass (1 pre-existing SSE subprocess failure in
this sandbox; unrelated).

Follow-up:
  - Migrate the actual module code to use the SQL tables instead of
    JSON files. Each module (quality.py, intelligence.py, monitors.py,
    etc.) needs a SQL-backed replacement. Estimated 4-6 hours.
  - Add Alembic for schema migrations instead of create_all().
  - Add Postgres-specific tuning when PRY_DATABASE_URL is set.

+"""Pry - SQLAlchemy database foundation.
-Replaces JSON file storage for production safety."""
 
+Replaces the 12 ad-hoc JSON file stores under $PRY_DATA_DIR with a single
+SQLite database (or PostgreSQL in production). Each legacy JSON store gets
+a SQLAlchemy model with a matching schema, and a one-shot importer for
+existing data.
+
+Why migrate:
+  - JSON files give no concurrency control. Two writes = corruption.
+  - No transactions. A partial write is permanent.
+  - No querying. Can't ask "all monitors on example.com".
+  - No relationships. Can't join a monitor with its alerts.
+
+Engine selection:
+  - Default: SQLite at $PRY_DATA_DIR/pry.db. Zero-config, file-based.
+  - Production: set PRY_DATABASE_URL=postgresql://... to use Postgres.
+    SQLAlchemy handles the rest; no code changes.
+
+Schema:
+  See the Model classes below. Each one corresponds to a former JSON store:
+    quality       -> QualityCheck
+    reviews       -> ReviewItem
+    intel         -> IntelSnapshot (already JSONL; now a real table)
+    costing       -> CostingEntry
+    freshness     -> FreshnessSnapshot
+    structure     -> StructureSnapshot
+    seo           -> SeoSnapshot
+    monitors      -> Monitor
+    monitor_runs  -> MonitorRun
+    accounts      -> Account
+    sessions      -> BrowserSession
+    reports       -> Report
+    reports_real  -> RealReport
+    training      -> TrainingDataset
+    pipelines     -> Pipeline
+    pipeline_runs -> PipelineRun
+    gdpr          -> GdprRequest
+    agency        -> Agency
+    agency_clients -> AgencyClient
+    referrals     -> ReferralClick
+    actors        -> Actor
+    actor_runs    -> ActorRun
+    llm_usage     -> LlmUsage
+    webhooks      -> Webhook
+    x402          -> X402Receipt
+
+This is a 24-model starter set. New models can be added incrementally as
+the corresponding JSON store is migrated.
