feat(server): multi-template MD→HTML with .zddc.d/templates cascade

The convert engine renders markdown→HTML/PDF through named doctype templates
selected by the document's `template:` front matter, with per-project/per-party
overrides.

convert package:
- embed.go now embeds the whole templates/ dir (all: prefix so _-prefixed
  partials are included) as an embed.FS; drop the single viewer-template.html +
  custom.css embeds. New TemplateSet type + DefaultTemplateSet(name) returning the
  chosen doctype + its partials.
- ToHTML/ToPDF take a TemplateSet; writeTemplateSetToScratch materialises the
  template + partials flat into the per-call scratch dir (pandoc resolves
  $partial()$ from the template's own directory).

handler:
- converttemplate.go: templateNameFromFrontMatter (YAML front-matter scan,
  sanitized to a bare basename) + resolveTemplateSet, which overlays
  <level>/.zddc.d/templates/<name>.html overrides onto the embedded defaults,
  walking docDir→fsRoot so a party dir beats the project-global dir. An override
  may replace a doctype, a partial, or add a brand-new doctype.
- buildAndStore threads fsRoot + source into the html/pdf paths.

build: pandoc/templates/ is the single source of truth; shared/build-lib.sh
sync_pandoc_templates mirrors it into the embed dir on every build (cmp-guarded,
stale-pruning). convert.TestEmbeddedTemplatesMatchSource fails on drift.

Tests: drift + DefaultTemplateSet (convert); front-matter parse + cascade
override precedence (handler). Full ./... suite green.
