fix: remove defaultAgentId fallback — require agentId from caller

agent-state, dispose, dial, performance, force-ready, unlock-agent
all required agentId from the request body now. No silent fallback
to OZONETEL_AGENT_ID env var which caused cross-tenant operations
in multi-agent setups (Ramaiah operations hitting Global's agent).

OZONETEL_AGENT_ID removed from telephony env seed list. Hardcoded
fallbacks (agent3, Test123$, 521814) deleted.
