Stacked on #185 (fix/ueb-typeform-rules), which adds the TextTranslator.isUebLiterary helper this uses. Merge that one first.

Problem

ASM's statements put fully capitalised notices, address blocks and bold notices in consecutive Word "List Paragraph" paragraphs. BrailleBlaster translated each paragraph on its own, so a passage was closed and reopened at every paragraph break.

Fix

The docx import marks List Paragraph items with utd:passageRun. Word's "List" and "List 2" items import as the same list items, but they aren't marked. When a passage at the end of one marked block carries on at the start of the next, GenericBlockAction translates the run in one liblouis call (the paragraphs joined by a newline), and each block keeps the cells that come from its own text.

• Capitals (matches Duxbury): one capitals passage indicator before the first word and one terminator after the last uppercase letter.

  before: ,,CVRXCU/OM]#JJDIHAD ,,"N#A     after: ,,,cvrxcu/om]#jjdihad "n#a
          ,,CVRXCU/OM]#JJDIHAD ,,"N#B            cvrxcu/om]#jjdihad "n#b,'
  

• Typeforms (Braille Formats 2016 §5.6, Rules of UEB 9.9.1): each paragraph starts with the typeform passage indicator, and the typeform is terminated only where it changes. This covers italic, bold, underline, script and the transcriber-defined typeforms. Two words across a paragraph break keep their word indicators.

  before: ^7,yr pay;t is late & y may [e a fee4^'    after: ^7,yr pay;t is late & y may [e a fee4
          ^7,call u td to set up a plan4^'                  ^7,call u td to set up a plan4^'
  

A passage that ends inside its paragraph, Normal and "List" paragraphs, headings, and non-UEB tables (Spanish, EBAE) are translated as before.

Known differences and limits

• Different from Duxbury on purpose (9.9.1): BR-78_lws page 3, and BR-10_lws / BR-39_lws page 5, where a bold paragraph runs into bold text in the next one. Duxbury closes the passage there.
• UEB 8.5.5 versus Duxbury: 8.5.5 says each paragraph of a capitals passage should also start with ,,,. This PR matches Duxbury (one ,,,) instead.
• Scope: only Word List Paragraph paragraphs. NIMAS, EPUB and other formats, and Word Normal paragraphs, will follow in a later PR.
• Editing: if you edit one paragraph of a run in the editor, only that block is retranslated. The paragraphs next to it update when they're retranslated.

Tests

DocxPassageRunTest (15 tests): the job examples, bold/italic/bold+underline runs, bold that ends partway through the next paragraph, two bold words, a run across a braille page break, and Normal and "List" paragraphs that are unchanged.
