feat(templates): render inline links in CV entry titles and subtitles

[DemchaAV]

Why

CV project rows and body text already render inline [label](url) Markdown as
clickable links (since v1.6.8), but experience/education entry titles were emitted
as plain text — so a [name](url) in an entry title (a project name, an employer)
showed up literally instead of linking. Subtitles were inconsistent: link-aware in the
canonical renderer, stripped in the compact and hand-rolled ones.

What changed

• MarkdownInline gains appendTransformed(rich, text, style, UnaryOperator<String>) —
  link-aware, applying the transform to the visible label and plain segments but never
  the URL — plus appendUpperCased (now a delegate) and appendIfPresent (the
  link-aware counterpart of appendPlainIfPresent).
• Entry titles and subtitles route through the link-aware helpers everywhere they
  render: the shared EntryRenderer and EntryCompactRenderer (all five variants,
  upper-case-aware), and the four presets that hand-roll their own titles —
  MonogramSidebar, SidebarPortrait, EngineeringResume, and MintEditorial
  (letter-spaced via appendTransformed(TextOrnaments::spacedUpper)). No CvEntry
  change.
• TimelineMinimal fuses each entry into one truncatable excerpt line and cannot carry
  a clickable link; it now strips the markdown to the label text instead of rendering
  [..](..) literally. The fused subtitle+date meta line in the MintEditorial /
  SidebarPortrait experience entries flattens the same way. Dates stay plain
  (out of scope).
• Backward-compatible: a title with no inline-Markdown syntax renders byte-identically —
  all CV visual-parity and layout snapshots are unchanged (no re-bless).

Verification

./mvnw -B -ntp clean verify -pl :graph-compose-templates,:graph-compose-qa -am →
BUILD SUCCESS, qa 666 tests, 0 failures; CV visual-parity + layout snapshots
unchanged.

• MarkdownInlineTest +5: URL preserved under upper-casing, transform hits the
  label not the URL, appendIfPresent emits prefix + link, blank/null is a no-op, and
  a plain title matches the old plainText().toUpperCase().
• New EntryTitleLinkTest (6): a [label](url) title becomes a link through
  EntryRenderer, the upper-cased EntryCompactRenderer (label upper-cased, URL
  intact), and the hand-rolled MonogramSidebar + EngineeringResume paths; the
  subtitle links too; and a plain-title control (asserted specifically, since the header
  contact block renders its own email/website links).
• A ModernProfessional render + PDF link-annotation check confirmed the entry-title
  URIs are present as clickable annotations in the output PDF.

Lane: templates (canonical). No engine or public-DSL change; links reuse the existing
RichText.link convention (they inherit the title's style, matching project-row links).
