i18n(ja): add the missing panel rows and recount localization

Review follow-up to the panel/dialog step: the composition-settings tabs
translate "Basic" and "Advanced" through `tr(variable)` and the Preview
transport translates "Play/Stop", but none of the three had a catalog
row, so they stayed English. Add them to the Japanese, Simplified and
Traditional Chinese catalogs and pin them in
`japanese_rows_translate_the_panels`.

The shared "Type" key means "kind" in the Project column and the Camera
Settings dialog, so the Chinese rows read 类型/類型 instead of 文字
("text").

Keep the graph button bar's automation labels English: translate only
the drawn label and tooltip, and translate the stored English strings
when the hidden-button menu draws them.

Recount the docs from the catalogs: 628 menu rows, 996 Japanese and 998
Chinese panel rows; count Simplified Chinese's 306 effect names in its
numerator (46%) and average the ten After Effects languages the table
actually names (21%, not the stale 27%). Update the measurement basis,
the cross-references in gaps.md and target-app-parity.md, and ROADMAP.
