Add strict channel tool flow coverage

[nickmisasi]

Summary

Expanded handler-level coverage for strict channel tool-calling flows that propagate channelToolsAutoRunEverywhereOnly from post props through tool approval/result handling, and fixed a lint-blocking staticcheck issue in OAuth notification formatting.

QA test steps:

• gofmt -l conversations/tool_handling_test.go conversations/conversations.go
• GOTOOLCHAIN=go1.26.1 /tmp/golangci-lint-bin/golangci-lint run ./conversations/...
• go test -count=1 ./conversations/...

Security Review: No findings

This PR contains:

1. A single-line lint fix in conversations/conversations.go converting WriteString(Sprintf(...)) to Fprintf(...) — functionally identical, no behavioral change.
2. ~317 lines of new test code covering the channelToolsAutoRunEverywhereOnly tool-calling flow.

No production logic is added or modified beyond the stylistic refactor. No new attack surface, no data flow changes, no auth/authz impact.
