docs: finish holding the documentation against the code

The first pass through A6 caught the dead file paths and the two GDPR
sections. A review pass walked every remaining claim and found eight
more that no longer describe the plugin.

The privacy notice carries a "last reviewed" stamp and commits, in its
own text, to keeping it accurate for the version it describes. It still
said v1.1.0 after the block that rewrote two of its sections.

Both documents announced two outbound network calls in their opening
paragraphs. The Lodestone font download went away in v1.0.4 and the
notice explains that further down, so the summary contradicted its own
body. There is one call, and it is BetterTTV.

The emote cache is `EmoteCacheV1/`, which the notice states correctly in
one place and wrongly in two others, two lines above a line this cycle
had already touched.

The list of buttons that open a browser named a Ko-fi page that appears
nowhere in the source, an issue tracker and a website that have no
button, and left out the Discord invite and the two Honorific links that
do. In a section that exists precisely to enumerate where a click sends
you, both halves matter.

The README described the pop-out input bar as an opt-in under a settings
section that does not exist. Neither does the switch: PopOutInputEnabled
has no reader, the input bar is unconditional, and the field belongs on
the deletion list. Said plainly instead.

Also: the export narrows by age, not by a date range, in both documents;
the tab is called About, not Info, and it has no per-translator list;
the sections are Colours and Integrations.

Plus a note the users affected by it deserve: the v24 migration switches
the privacy filter off where it was on with nothing selected, and until
now that was only in the log.
