fix(feed): header on one line, avatar padding explicit, icon/label aligned

Three related layout polish issues.

1. Avatar + name + time splitting to two lines

   Fixed by collapsing the "·" separator + time into a single Text
   component (was three sibling Texts). RN occasionally lays out
   three-Text-sibling rows oddly when the name is long because each
   Text measures independently. With the separator glued to the time,
   there's one indivisible chip for "·  2h" that flexShrink:0 keeps on
   the row; the name takes the rest and truncates with "…" if needed.
   Also wrapped the name + time in a flex:1 Pressable (author tap
   target) so the row width is authoritative.

2. Avatar flush against the left edge

   The outer Pressable's style-function paddingLeft was being applied
   but the visual offset felt wrong because avatar has no explicit
   width. Added width:44 to the avatar's own Pressable wrapper so the
   flex-row layout reserves exactly the expected space and the 16-px
   paddingLeft on the outer Pressable is visible around the avatar's
   left edge.

3. Like / view count text visually below icon's centre

   RN Text includes extra top padding (Android) and baseline-anchors
   (iOS) that push the number glyph a pixel or two below the icon
   centre in a flex-row with alignItems:'center'. Added explicit
   lineHeight:16 (matching icon size) + includeFontPadding:false +
   textAlignVertical:'center' on both the heart button's Text and the
   shared ActionButton Text → numbers now sit on the same optical
   baseline as their icons on both platforms.
