refactor(builder): remove dead component settings UI

Each component defined a .craft.related.settings panel that was never
rendered -- the right panel renders only GuidedStyles (per-type
*StylePanel components), never .related.settings. Removed all dead
settings components across every component, their settings-only helpers
(including the dead uploadToWhp/showBrowser/handleBrowse asset-browse
blocks in Logo/Navbar/VideoBlock/FeaturesGrid, and CtasEditor in
_cta-helpers), and dropped the now-empty related keys. Render output,
.craft props/rules, and toHtml statics are unchanged.
