Render $...$ / $$...$$ LaTeX in markdown (READMEs, issues, comments) via
client-side MathJax, with detection handled server-side by the Hugo
passthrough extension plus a custom renderer.

Pipeline:
- extension/math.go wraps each math span in <span class="math inline|
display"> carrying the raw LaTeX with MathJax \( \) / \[ \] delimiters.
passthrough handles single-line "$$...$$" blocks and protects markdown
inside math; a Pandoc-style guard (no space-padding, no digit after the
closing $) keeps currency like "$5 ... $10" from being parsed as math.
- layouts/base.html loads MathJax (v4.1.2, tex-svg) on demand, only when a
page contains span.math, and typesets just those nodes. Accessibility
options are disabled as an initial, conservative implementation.
- the sanitizer preserves the math carrier spans.
- MathJax is vendored at build time alongside mermaid (flake.nix, the nix
static-files package, and the localinfra script).

multiple `defer rows.Close()` call in same scope can be dangerous as
underlying value will change.
avoid that by splitting reverse-mapping queries into scoped blocks.

This can catch `pages.Notice` responses which is not a successful
request. We refresh the page on successful case, so it's fine to not
refresh the form.

Introduce aturi->url maker in `pages.Pages`. This can be used throughout
the codebase later.
