fix(bitdefender): third-pass - companies pagination, connect-retry, Retry-After ceiling, ctx mgr

Browse Source 
Remaining LOW/NIT items from the second review pass:
- list_all_companies() paginates the company list; sweep-all + refresh_inventory
  no longer truncate a >100-company tenant.
- Pre-send connection failures (httpx ConnectError/ConnectTimeout; urllib URLError
  not wrapping a timeout) are now retried as 'connect' - always safe (no side
  effect) even for non-idempotent writes; ambiguous read-timeouts stay idempotent-gated.
- Explicit Retry-After honored up to RETRY_AFTER_MAX_SECONDS (120s) instead of the
  30s exponential cap, so a server-mandated cooldown isn't cut short.
- GravityZoneClient is now a context manager (__enter__/__exit__ -> close()).
- incident-status/note reject an empty --set-json (rc2), matching account-update/notif.
- selftest: +connect/Retry-After/ctx-mgr unit coverage, incident empty-json assertion. 79/79.
