refactor: move tests into tests/<domain>/ layout
Applies the plan's C5 step: git mv every test per the domain-reorg
move-map (movemap-m50.txt) into tests/{agent,analyzer,auth,dashboard,
github,middleware,models,reviewer,sandbox,slack,tools,webhooks}/, plus
the 13 fork-only placements from the scoping report §2c (Atlassian
webhook tests -> tests/webhooks/, test_atlassian_connect.py and
test_auth_error_leak.py -> tests/auth/, jira/confluence util tests ->
tests/tools/, test_repo_binding_isolation.py -> tests/sandbox/,
bot-identity/autofix tests -> tests/github/).

Path-only move: the only content edits are parents[1] -> parents[2]
fixes in test_e2b_integration.py and test_daytona_integration.py,
required because their __file__-relative ROOT path gained one more
directory level in the move.

Monkeypatch retargets for these files were already completed in C4;
none remained outstanding here.
