Subject: feat: import MyST swap mechanism + content for sagitta (replaces
 #1886)

Replaces the broken #1886 with a fresh, properly-converted MyST set for
the sagitta (1.4.x) docs, mirroring what landed for circinus via #1897.

This PR:

- Re-imports 210 md-*.md files for sagitta. Source: ran the pipelines
  rst-to-myst converter (chrisjsewell/rst-to-myst v0.4.0, with pandoc
  fallback) on sagittas RST. Post-processed via the pipelines
  postprocess stage (10 ordered fixes for blanks, admonitions, label
  hyphens, pandoc artifacts, structural blanks, linter markers).
  Compared to the broken #1886 content (which was left over from an
  earlier stage-1-only run): zero raw `<div class=>` remnants.

- For 23 stems where sagittas RST is byte-identical with currents RST
  (mostly stable policy/protocol pages and the 404 page), reuses currents
  already-validated md-*.md content rather than re-converting.

- Drops cli and installation/cloud/aws from sagittas swap set: their
  RST has SEVERE/4 "Title level inconsistent" errors that crash
  rst-to-myst; they need an independent RST-source fix and are kept as
  RST-only for now.

- Adds the per-page swap mechanism: scripts/swap_sources.py,
  scripts/import_myst.py, the matching tests under tests/, _swap.txt
  with 210 stems, _ext/vyos.py MyST renderer fallback, Makefile
  swap-wrapped targets, .readthedocs.yml swap pre/post hooks.

- Adds 187 .webp images and removes 235 superseded .jpg/.png/.jpeg
  static assets; flips html_logo to vyos-logo.webp.

- Adds the MyST swap-related blocks to docs/conf.py only:
  myst_enable_extensions, myst_fence_as_directive, md-*.md exclude
  patterns, _swap_exclude.txt reader, _prefer_webp and _copy_md_sources
  setup hooks. github_version fallback set to 'sagitta' to match the
  branch (parallel to currents 'current' and circinuss 'circinus').

Deliberately excluded (per user direction):

- llms.txt and sphinx-llms-txt / sphinx-sitemap config: these will
  land separately for sagitta via #1870 plus a new sagitta-specific
  llms.txt template PR. The conf.py here does not pull those extensions
  in, so the build does not depend on the new pip packages.

Verification before pushing:

- 210 md-*.md = 210 _swap.txt stems = 210 RST siblings on sagitta (1:1:1).
- 0 files contain raw `<div class=` (the breakage that took down /en/1.5/).
- conf.py copyright/version/release preserve sagittas values
  (2024 / 1.4 / "1.4.x (sagitta)") - not currents.
- html_title from currents conf.py removed - PR #1880 is the right place
  for sagittas branch-localized title.

Supersedes / closes on merge:

- #1886 (broken converter output, would break /en/1.4/ if merged).
