[logging] inspector: convert second-wave hosted routes to typed events

[Vu-John]

Adds mcp.tool.execution.failed to the event map and emits it from the
/execute callback catch. Converts web/oauth.ts proxy, metadata, and
debug/proxy routes to emit mcp.oauth.proxy.failed. resources.ts and
prompts.ts have no explicit error paths beyond withEphemeralConnection
delegation so are left unchanged.

Walkthrough

The changes add structured error logging to three distinct failure points. OAuth proxy and metadata endpoints now emit categorized failure events containing the target hostname, phase indicator, and error classification. The tool execution endpoint adds similar logging when tool execution fails, capturing tool and server identifiers alongside error codes. A corresponding request event type is introduced to formalize the tool execution failure log schema.
