revert(themes): hide feed name at narrow viewports (#8838)

Reverts #8801 (keeping its incidental blank-line cleanups) and #8815, restoring icon-only feed column on mobile (#8814).

I filed the original PR thinking the icon-only behavior was an inconsistency bug versus the configurable `topline_website` setting, not realizing it was a deliberate mobile choice. The `clamp()` cap helped, but the column still takes space the title could use, and on phones icon-only is the better tradeoff.

A distinct narrow-viewport setting for `topline_website` was raised as a future improvement.

* Revert "fix(themes): cap website column at narrow when feed name is shown (#8815)"

This reverts commit af6a5006382340865a1d68b0c3ff944fe20b8456.

* Revert "fix(themes): show feed name at narrow widths when configured (#8801)"

This reverts commit 9ff4aec368ba33e2ccab379f5fb1bdf4dae32da6.
