mAi: #98 - move Auto-rule resolved name to its own row

The Auto-mode resolved rule name was rendered as an inline-flex pill
that sat visually crammed next to the [Eigene Regel eingeben] toggle.
Promote .rule-mode-auto to a full-width block-level flex row (width:
100%, margin-top: 0.35rem) so it sits cleanly on its own line beneath
the toggle, and render the rule label via the canonical
formatRuleLabelHTML helper so the citation gets the muted-secondary
styling from rule-label.ts.

Applies to both /deadlines/new and /deadlines/:id edit form. Custom
mode (free-text input) is unaffected — the input already filled the
column.

Refs: m/paliad#98 (t-paliad-267), addendum to t-paliad-258 / m/paliad#89.
