fix(editor): keep section headings separate from scripture

[henrique221]

Superseded by #475 after renaming the branch to fix/432-section-heading. The code is unchanged.

Section Heading now inserts a paragraph with its own words before the selected verse. I also preserve headings through editing, autosave, reloads and textarea edits. Heading level changes save explicitly because the editor misses that change event for simple headings.

This depends on fluent-api#319, which depends on fluent-api#305. Deploy the API support before this web change. It uses the existing markers.headings contract and adds no endpoint or migration.

Validation: pnpm precheck passed with 481 tests. The production build and docs check passed. I also checked insertion, direct editing, level changes, invalid-text recovery and reloads in the real browser, then verified web rows against the API schema, serializer and real USFM parser. Heading words stayed outside every verse, including ordered titles, poetry and an empty verse.

Structural edits reload the editor and reset its undo history, as existing scoped formatting does. The behavior and API dependency are documented in docs/features/section-headings/design.md.

Fixes #432.

The change adds standalone section headings to verse markers and USJ conversion. Editors can insert, edit, validate, and remove headings. Formatting, textarea editing, autosave comparison, localization, and regression coverage now preserve heading data.

Link the validation message to the input.

The error paragraph is not referenced by the Input. Screen reader users who move focus back to the field after the alert do not hear the reason. Add aria-describedby when invalid is true, and give the message an id.
