chore: v0.1.5 — wp.org reviewer-feedback fix

Reviewer flagged inc/about.php line 19 — an inline <style> block —
asking us to use wp_enqueue_style instead. Per their hint that the
team may not list every instance of an issue, fixed the entire CSS
inline-styling pattern across the plugin:

- inc/about.php: <style> block (lines 19-59) → moved to buddy.css
- inc/about.php: <span style="color:#646970; font-weight:400;">
  → .buddy-about-intro__version class
- inc/about.php: <p style="margin-bottom:0;"> → .buddy-about-intro__cta
- inc/settings.php: <form style="..."> → .buddy-settings-form class
- inc/settings.php: <h2 style="margin-top:0;"> → scoped under form class
- inc/admin-page.php: <p style="max-width:720px;">
  → .buddy-admin-description utility class

The only remaining inline style is in inc/dashboard-widget.php at the
stat-bar width — that is a runtime-computed %d value, legitimately
inline.

The buddy.css file was already enqueued on the About / Settings /
Admin / Dashboard pages via the existing buddy_enqueue_admin_assets
function, so no new enqueue logic was needed.
