fix(dashboard): equal-height cards — stretch + fill instead of ragged

The dashboard content grids used alignItems:"start", so cards in a row sized to
their own content (ragged bottoms). Switch to alignItems:"stretch" so each row
shares one height, and make the wrapped cards actually fill the cell:

- DashProfile / DashSessions: motion-div + Card height:100% (the inner card was
  shorter than its stretched cell).
- Right column (Aktivní projekty + Nabídky): cards flex:1 so the stacked pair
  fills the column to match the neighbouring single cards.

CSS-only; no logic change. tsc clean, lint 0, 669 tests pass. Verified live via
Playwright (3-col row cells equal at 607; bottom 2-col cards equal at 257).
