Docu cleanup

Minor cleanups across the codebase: switch current_user.get_last_language() to current_user.last_language to use the attribute directly; fix indentation in app mail init comment; correct typo in module-base.js comment; add IntersectionObserver root comment in tiles.js; small content/metadata and formatting edits in several nihongo lesson markdown files (add keywords, correct kana/phrasing, remove extraneous separators and fix trailing newlines); and add a brief comment in the lesson-directory template. These changes improve readability, searchability, and correctness.
