fix(Tabs): remove width/height 100% from TabsHost fillParent style

The fillParent style on TabsHost uses `flex: 1` together with
`width: '100%'` and `height: '100%'`. The explicit width/height
prevents TabsHost from participating in flex layout with sibling
views, because '100%' forces it to take the full parent size
regardless of other flex children.

This makes it impossible to place persistent UI elements (e.g. a
banner ad) alongside NativeTabs in a parent flex container — the
tabs always cover the full screen.

Removing width/height and keeping only `flex: 1` lets the native
component fill the remaining space after siblings, while the native
iOS (NSLayoutConstraint pinning) and Android (MATCH_PARENT) layout
still correctly sizes the tab controller within TabsHost bounds.
