settings-save-row: the Settings form is the left column

The owner chose Variant 2 on 2026-10-16 ("форма в левой колонке, кнопка
под своими полями"); the mockup is f95c553. Server › Settings: the form
wraps only the left column - Log retention, Notifications and Save
settings under them - and the right column, outside the form, holds
Notification mail and the read-only Sending rate limits. The boxes are
renumbered column by column (Notifications 02, Notification mail 03,
Sending rate limits 04). The fields, their names and the POST are
unchanged.

Tests: the page's outline matches the mockup's (TestPanelOutlinesMatchMockups);
go vet + go test (26 packages) and make e2e on the test server for this
tree.

CHANGELOG [Unreleased]; roadmap row done, its section quotes the choice.
