Fix WS Tool links, examples, sidebar

- Update docs links for all methods.
- Add some missing methods.
- Add an icon for Clio-specific methods.
- Move the long list of ledger_entry examples below other types so those
  ones are not as buried.
- Remove unused old JS files.
- Make method list sidebar self-scrolling like docs TOC sidebar, so that
  links to methods lower in the list don't scroll the main UI up off the
  visible part of the page.
- Fix #2470.
- Fix a broken 'try it' link on the amm_info page that was causing an
  error page to display when clicked.
