fix(analysis): align summary card amounts to a common baseline (#515)

## What

In the transaction **analysis drawer**, the summary cards' amounts
weren't lining up horizontally: the **Avg / day** card's label row holds
the day-editor button (a 24px icon button), making that row taller than
a plain text label, so its amount sat lower than **Total spent**.

## Fix

Give every summary card's label row a fixed `h-6` (matching the
icon-button height), so all label rows are the same height and the
amounts share a common baseline. Amounts were already the same size
(`text-lg`); this just equalizes the vertical space above them.

Applies to all summary tiles — expense mode (Total spent / Avg per day)
and income mode (Income / Expenses / Net / Margin).

## Before / After
- Before: Avg/day amount offset below Total spent.
- After: both amounts aligned on the same row.

Frontend tests (9) pass; eslint + prettier clean.
