Add renumber_all_blocks + fix sequential_numbering check for bold format

block_writer: new renumber_all_blocks() function that renumbers all
paragraphs across all blocks sequentially (1, 2, 3...). Handles both
plain "N." and bold "**N.**" formats. Added missing 'import re'.

qa_validator: sequential_numbering check now matches bold-formatted
numbers (**N.**) in addition to plain (N.).

Tested on Hecht: renumbered 115 paragraphs across 7 blocks, QA 6/6.
