cleanup: unify template-lint visual + drop 3 hardcoded color literals

Two separate places (Settings filename templates + clip-cutter
modal custom template) had their own lint state. Each set the
colour by JS as `lintNode.style.color = "#8bc34a"` (green for OK)
or `"#ff8a80"` (red for unknown placeholder). Same intent, different
implementations, different shades than the rest of the app
(--success #00c853 + --error #ff4444).

Extracted to a shared .template-lint class with .ok / .warn modifiers
driven by the canonical CSS vars. The renderers now swap classNames
instead of inline colours.

Also picked up the stale `color: #888` on filenameTemplateHint and
replaced with the existing .form-note utility class (which uses
var(--text-secondary)).

The old .clip-template-lint rule stays as a no-op alias for safety,
but its hard-coded #8bc34a is removed — colour now comes from
.template-lint.ok / .warn. Three hard-coded hex literals retired,
two state branches consolidated, semantics now track the global
palette.
