feat(serve): stream per-iteration usage events for live context gauges

[jkyberneees]

Summary

odek serve previously reported token economics only on the done event (once per user prompt), so WebSocket clients like bodek could only refresh their header context gauge at the end of a run. This PR streams a usage event after every LLM turn, plus two pre-existing test-suite fixes that were blocking a green run.

Changes

• feat(serve): stream per-iteration usage events — IterationCallback in cmd/odek/serve.go now emits {"type":"usage","contextTokens","outputTokens"} (cumulative for the run) after every LLM turn, alongside the existing thinking streaming. Documented in the Server → Client event table in docs/WEBUI.md.
• test(browser): auto-approve network egress in hermetic tests — TestBrowser_Navigate blocked forever on an interactive TTY approval prompt ([A]pprove [D]eny [T]rust session:) because newTestBrowserTool set NonInteractive: allow, which ActionFor never consults. Now allows the network_egress and system_write (loopback httptest URLs) risk classes directly, matching the allowAllDanger idiom. go test ./cmd/odek/ completes non-interactively again.
• test(config): scrub ODEK_ env leakage via TestMain* — 8 TestLoadConfig_* tests failed when the developer's shell exported ODEK_* vars (ODEK_MODEL, telegram vars, …), which leak into LoadConfig through os.Getenv. A TestMain scrubs ODEK_* (and legacy DEEPSEEK_API_KEY/OPENAI_API_KEY) before the run; per-test t.Setenv calls are unaffected.

Testing

• go vet ./... — clean
• go test -race -count=1 -run 'TestServe_E2E_(UsageEvents|TokenStats|LiveToolEvents)' ./cmd/odek/ — ok (new TestServe_E2E_UsageEvents asserts ≥2 usage events arrive before done: 100/20, then 300/60 cumulative)
• make test (internal packages) — ok
• go test -short -count=1 ./cmd/odek — ok (27s, no hang)
• golangci-lint run ./cmd/odek/... ./internal/config/... — 0 issues
• internal/config verified green with both a polluted shell (ODEK_MODEL=k3 ODEK_TELEGRAM_BOT_TOKEN=x …) and a clean one
