686f6c61 2bc9ed9f23 fix(mcp): fully redact credential headers in MCP probe errors and test display (salvage #97466)
`hermes mcp test` resolved Authorization headers and printed first4***last4
— still a reusable credential fragment — and probe exceptions that echoed
`Authorization: Bearer <value>` reached the CLI error line and the dashboard
`POST /api/mcp/servers/{name}/test` response verbatim.

Redact once at the `_probe_single_server` raise seam so every consumer
(`mcp add`, `mcp test`, `mcp login`, `mcp configure`, the dashboard probe,
`hermes doctor`, catalog probes) prints already-safe text. Recognized
credential header fields (Authorization/Proxy-Authorization plus
agent.redact._SECRET_HEADER_NAMES) have their complete value replaced with
***; bare Bearer/Basic/Token/Digest spans are covered; the generic redactor
runs force=True as a second pass. CLI header display fails closed: only pure
${ENV} template values print.

Salvaged from PR #97466 by @686f6c61 (base predated the mcp_config/web_routers
decomposition; re-applied onto current main, test seams repointed to the
defining modules tools.mcp_tool_loop / tools.mcp_tool_lifecycle).

Inspired by Claude Code 2.1.268: "Fixed /mcp and /plugin server details,
claude mcp list/get, and MCP login errors showing secrets resolved from
${VAR} placeholders in MCP configs."

Fixes #97460
