Moves the Unreleased lines into a 2.3.0 section dated 2026-10-22, with a short intro and the compare links. Part of BITS-384

• The editor lines pointed to stacked PRs that were closed into Rebuild the form editor as one document #282. They now say Rebuild the form editor as one document #282.
• Two pairs of lines said the same thing twice and are merged: too-long answers (Refuse a too-long public answer before saving it #293, Say when an answer is too long to store #294) and dashboard links with an old filter (Add each form's latest submission date to the form list API #242, Search, filter and sort the form list #248).

Tested: only CHANGELOG.md changes against main.

Looks good at ac58605. Text only, checked against origin/main (0 commits behind).

• Nothing lost: the only removed lines are merges. #294 joins #293's line in Fixed, and #242's "unknown filter or sort shows your forms" sentence joins #248's line, now (#242, #248). The meaning is the same.
• Re-pointing is right: #268, #271 to #277 and #279 to #281 are closed, #282 is merged, and #282's body lists each of them as included. #269 and #278 were merged on their own and keep their numbers.
• 2 Upgrade step lines (#242 sort, #296 php.ini), matching the intro. Both are in the release notes' "Before you update".
• The #296 line is first under Security. The footer links and the new empty [Unreleased] are right.
• Every point in the release notes draft matches a line in the 2.3.0 section. Only "Back up your database and APP_KEY first, as always" is not in this section, which is fine as general advice.
