kshitijk4poor 676236bb1d fix(agent): honor custom CA certs on aux client + harden TLS resolution
The salvaged fix wired per-provider ssl_ca_cert / ssl_verify (and
HERMES_CA_BUNDLE) into the MAIN OpenAI client. This follow-up:

- Auxiliary client parity: process_bootstrap.build_keepalive_http_client
  accepts and forwards verify; auxiliary_client._resolve_aux_verify mirrors
  the main-client TLS resolution (via load_config_readonly, the read-only
  fast path) so compression/vision/web_extract/title-gen/session_search
  honor the same per-provider CA. Without this, chat worked against a
  private-CA endpoint but every auxiliary call still failed APIConnectionError.
- switch_model now reads custom_providers from live config (load_config_readonly)
  instead of the init-time agent._custom_providers snapshot, so ssl_ca_cert /
  ssl_verify edits are honored on mid-session model switch — matching the
  context-length reload (#15779).
- Drop the dead client-level verify= where a custom httpx transport is used
  (httpx ignores it there); verify lives on the transport. Fix docstrings.
  Applies to both run_agent._build_keepalive_http_client and process_bootstrap.
- resolve_httpx_verify: add CURL_CA_BUNDLE to the env chain (consistency with
  agent/ssl_guard._CA_BUNDLE_ENV_VARS) and emit a loud logger.warning naming
  the endpoint whenever ssl_verify:false disables verification.
- get_custom_provider_tls_settings: case-insensitive base_url match (config
  dedup already lowercases; scheme/host are case-insensitive) so a mixed-case
  entry doesn't silently drop its CA. Exact match preserved — no prefix bypass.
- Demote best-effort except Exception: pass in agent_init/switch_model to
  logger.debug(exc_info=True).
- Tests for aux verify forwarding, _resolve_aux_verify, case-insensitive
  match, and prefix-bypass rejection.

"""Regression: auxiliary-client keepalive httpx client must honor custom CA bundles.
The main OpenAI client resolves per-provider ``ssl_ca_cert`` / ``ssl_verify`` and
``HERMES_CA_BUNDLE`` via ``agent.ssl_verify.resolve_httpx_verify``. Auxiliary calls
(compression, vision, web_extract, title generation, session_search) build their own
keepalive client through ``agent.process_bootstrap.build_keepalive_http_client`` and must
apply the same TLS settings — otherwise an HTTPS custom_providers endpoint signed by a
private CA works for chat but fails ``APIConnectionError`` on every auxiliary task.
