Table was not rendering correctly.

Fix Sphinx docs: replace csv-table with list-table for formatting functions

The documentation table of formatting/query functions was not rendering
because `.. csv-table::` requires strict RFC4180 CSV escaping. The table
contains nested quotes, inch marks (e.g. `3' - 0"`), backticks, and code
examples, which cause the CSV parser in docutils to treat rows as malformed
and drop the entire directive.

Replaced the directive with `.. list-table::`, which parses reStructuredText
instead of CSV and safely supports inline code, quotes, and multi-line cells.

Also moved the examples text outside the directive block and ensured a blank
line after the table so Sphinx does not interpret following paragraphs as
table rows.

No content changes — documentation now renders correctly.
