style(footer): align + brand sub-title typography across columns

One-shot mu-plugin patches the Footer template (#46) :
- Column sub-titles (Solutions / Company / Legal / Contact) now use the
  eyebrow style : gold, uppercase, 0.75rem, 0.1em letter-spacing — matches
  the section-eyebrows used across content pages.
- Brand heading (ASTERION VR) downsized to 1.125rem so it stops dominating
  the row; tagline muted to text-tertiary 0.875rem.
- Columns wrapper set to align-items: flex-start with consistent 3rem gap
  → all sub-titles sit at the same vertical baseline.
- Each column container tightened to 0.5rem rowGap (less air between
  heading and links).

Patches both content_2 (JSON, source) and footer_2 (serialized, mirrored
by the REST bridge). Idempotent.
