sh eed1bf14c6 web: extract shared web module from smp-server (#1723)
* web: extract shared web module from smp-server

Move web serving infrastructure (warp, static files, HTML templating)
from apps/smp-server/web/Static.hs into library modules:
- Simplex.Messaging.Server.Web (generic web infra + templating)
- Simplex.Messaging.Server.Web.Embedded (TH-embedded assets)

Move static assets from apps/smp-server/static/ to
src/Simplex/Messaging/Server/Web/.

Move EmbeddedWebParams/WebHttpsParams from Server.Main to Server.Web.

Keep SMP-specific rendering (serverInformation) in apps/smp-server/SMP/Web.hs.

generateSite is now generic: takes pre-rendered HTML + link page paths,
enabling reuse by XFTP and NTF servers.

* web: add tests for templating engine

Tests for render, section_, item_, and timedTTLText functions
in Simplex.Messaging.Server.Web module.

* web: add serverInfoSubsts, serveStaticPageH2, safe port parsing

* web: rename SMP.Web to SMPWeb, remove SMP subdirectory

* fix(web): section_ collapsing sections with Just "" content

Commit e48bedea ("servers: fix server pages when source code is not
specified") changed section_ to treat Just "" the same as Nothing -
collapsing the section. The intent was to handle the sourceCode case
(empty string when not specified), but the guard
`not (B.null content)` also broke operator, admin, complaints, and
hosting - all of which legitimately use Just "" as a
section-present marker.

Before (correct):
  Nothing -> before <> next
  Just content -> before <> item_ label content inside <> ...

After (broken):
  Just content | not (B.null content) -> ...
  _ -> before <> next

Restore the original behavior: only Nothing collapses a section.

* refactor
