frontend: rewrite the SSR content service in Go (#28)
Ports frontend/ (Jinja2/FastAPI, ~1180 LOC) to Go with html/template. No
climate math, no DB, no auth -- every route fetches from the backend's
/content/* API.

Verified with a golden-HTML diff, not just unit tests: both the Python
original and the Go rewrite were run against the same committed fixtures
and every route compared byte-for-byte, confirmed programmatically. That
process caught defects unit tests alone missed, since map[string]any has
no compile-time field check:

- Render-context keys were snake_case throughout while the templates read
  PascalCase fields. A missing map key doesn't error, it silently renders
  empty -- title, meta description, canonical URL, OpenGraph tags, and the
  homepage's entire ranked list were blank on every page despite every
  route returning 200. Fixed by renaming every key to match each
  template's own documented field contract, and passing API structs
  straight through wherever their fields already matched (removes a whole
  layer of future drift risk).
- Three pages 500'd: ToolHref needed a composed href, not a bare
  "lat,lon" fragment; the records table needed the raw API struct.
- JSON-LD was double-encoded: <script type="application/ld+json"> is
  JAVASCRIPT context to html/template's escaper regardless of the
  script's type attribute, so template.HTML gets re-escaped as a quoted
  JS string. Needed template.JS. The glossary term page's JSON-LD was
  never built at all -- added.
- html/template silently strips literal HTML and JS comments from parsed
  output (verified in isolation) -- both need a FuncMap function
  returning template.HTML/template.JS to survive.

Packaging: 187MB -> 22.6MB. Two defects caught before reaching a host: the
Swarm stack's entrypoint override with no explicit command drops the
image's CMD entirely (every deploy would have exited 127), and
COPY --chown by name fails under the classic Docker builder on Alpine.
Both fixed.

go build/vet/test -race clean; docker build passes its embedded test step
under both BuildKit and the classic builder; shellcheck 0 findings.
