fix: make orchestrator teardown timeout configurable (closes #435)

Resolves via ENV VAR -> orchestrator DB config -> default (30 s, up from 5 s):
  BOT_BOTTLE_ORCHESTRATOR_TEARDOWN_TIMEOUT_SECONDS
  teardown_timeout_seconds key in new orchestrator_config table (bot-bottle.db)

New OrchestratorConfigStore (same DbStore/TableMigrations pattern as the
registry) stores the DB-level setting. resolve_teardown_timeout() implements
the priority chain and is called at stack.callback registration time in all
three backends (macos_container, docker, firecracker).
