video discover: move 'My services' out of the page-wide bar (it's a rail builder, not a filter)

'My services' only builds the optional 'On your streaming services' rail, but sitting under
the 'Across Discover' header it read as a page-wide filter (user confusion: 'i thought it
affected the whole page because that's what it says'). Moved it to its own self-describing row
('pick what you subscribe to — adds a rail to your feed') below the bar. 'Across Discover' now
holds only the genuinely page-wide controls: Hide owned + Languages. Markup/CSS only — the
data-vdsc-myprov hook is unchanged.
