Restore IssuesVisualizer redesign reverted by merge 67ce419 and re-apply
Needle triage/test additions. Migrate all remaining screens off the MD3
palette, raw Tailwind colors, gradients and Material Symbols. Remove the
legacy theme block and fonts, drop the duplicate tab strip, rebuild
TelemetryFilters on FilterBar, and document status in AGENTS.md.

- Add static/otel-rum.js: a framework-free browser script that captures
uncaught errors, unhandled promise rejections and failed resource loads,
translating them into OTLP log records POSTed to the existing /v1/logs
endpoint (source: frontend attribute) so they flow through the same
history/search/issue pipeline as backend telemetry.
- Add correlation-id support: traceHeaders() (manual) and same-origin
fetch auto-instrumentation inject a W3C traceparent header, so a
frontend error and the backend spans it triggered share a trace id and
can be found together via GET /api/traces/{traceId}.
- Add CORS handling (withCORS in cmd/server/main.go) on the OTLP HTTP
endpoints, required for any browser-origin POST.
- Add an optional shared ingest key (OTEL_INGEST_KEY, via '?key=' or
X-Otel-Ingest-Key) and a per-IP rate limit (20 rps/burst 50) on OTLP
HTTP ingestion, to scope/protect a public endpoint fed by a browser
script. Verified end-to-end (CORS preflight, cross-origin POST, ingest
key enforcement, rate limiting) against a running server.
- Serve static/otel-rum.js and agents_example.md as static HTTP routes so
both the script and the agent instructions doc are fetchable directly
from the base URL.
- Ignore the separately-cloned otel-ui/ frontend repo (has its own .git;
not meant to be nested into this repo's history).

- Add internal/issues.Tracker: fingerprints (kind, service, title) into
deduplicated Issues with count/firstSeen/lastSeen/affected services and
bounded sample occurrences, evicting the least-recently-seen issue once
a cap is reached.
- Add internal/collector/issue_extract.go to pull issues out of ingested
OTLP data: spans with an error status (preferring exception.type/message
from an "exception" event, falling back to the span status message), and
logs at ERROR/FATAL severity (by severity number or text).
- Wire extraction into Collector.ConsumeTraces/ConsumeLogs and expose
GET /api/issues and GET /api/issues/{id}.
- Fix a pre-existing data race in the collector test's mockStore (unsynced
access to entries while addToHistory appends asynchronously), found via
`go test -race` while adding the new issue-tracking tests.
- Update docs/PLAN.md, README.md and agents_example.md for the new API.
The UI "Issues" tab itself lives in the separate frontend project that
builds this server's dist/ bundle; this commit only covers the backend.

- Fix /api/history/{type} to search the full persistent store instead of
only the bounded in-memory ring buffer, so filtered history isn't
silently truncated.
- Add structured type/since/until filters to /api/history/search and
/api/history/wait, alongside the existing free-text query.
- Add GET /api/traces/{traceId} to fetch all entries for a trace in one
call instead of relying on substring search.
- Rate-limit /api/history/wait per client IP.
- Add docs/PLAN.md tracking the phased improvement plan; update README
and agents_example.md for the new/changed endpoints.
