feat(remotion): +2 scene blocks — LogoReveal (logo motion) + StatCounter

Grows the scene-block library toward full template-type coverage:
- LogoReveal: premium logo-motion — spring scale-in + glint sweep over the logo
  (image upload or a branded play-mark placeholder) + brand text + tagline, on the
  shared 2.5D Three backdrop. Fields: logoUrl, brandText, tagline.
- StatCounter: animated count-up to a target (English-digit value → Persian
  display) + suffix + label. Fields: value, suffix, label.

Registry now has 8 blocks. Both verified via FlexStory props-override stills.
