ktlint: a multiline .border() left the next '.' orphaned, exactly as #3110 records

`standard:chain-method-continuation` on `LinkPreviewRow.kt:83`. The `.border(…)`
call took three arguments across four lines, and the `.padding(…)` after it then
began a line with a `.` — which the rule only accepts glued to the closing
paren, `).padding(…)`.

Issue #3110 hit this same rule in `NoteCard.kt` and recorded the fix: do not
write the multiline element. Naming `shape`, `padH` and `padV` first collapses
`.border` back to one line and removes the duplicated RoundedCornerShape at the
same time, which is better than what ktlint was willing to accept.

Also did what #3110's verification note says to do rather than fixing only the
line the linter named: scanned every Kotlin file this branch touched for the
same shape — a multiline chain element followed by a `.` on a new line — and
found no others. ktlint reports one violation and stops, so a second would have
cost another full Android lane.
