test: add 29 new tests for cleanup, orchestrator, findings, tool registry, models

- cleanup.rs: 8 tests — routing logic, skip conditions, missing config errors
- orchestrator.rs: 7 tests — summarize_tool_output (screenshot strip, truncation, recursion)
- findings.rs: 6 tests — empty state, severity grouping, SAST correlation, evidence table
- tools/mod.rs: 4 tests — registry completeness, schema validation, browser action enum
- models.rs: 4 tests — TestUserRecord serde, IdentityProvider variants, BSON roundtrip

Total: 326 tests (was 297)
