Show remaining template card features below when position is inline

[piitaya]

Description

When features_position is inline, the template card only renders the first feature and silently drops the rest. This ports the tile card behavior from home-assistant/frontend#53310 and home-assistant/frontend#53631: the first feature stays inline next to the name, and the remaining ones are laid out below in two columns with a divider.

The two column layout relies on the hui-card-features columns property introduced in HA 2026.9, so the new behavior is gated on atLeastHaVersion(2026, 9). On older versions the card keeps showing only the first feature. getCardSize/getGridOptions count the extra rows the same way the tile card does.

Motivation and Context

Keep the template card aligned with the tile card. The editor lets you add several features in inline mode and nothing happens, which reads as a bug.
