* [Android] Migrate private NTP to Leo tokens and fix VPN icon visibility
- Drop Brave-local duplicates of ic_product_vpn / ic_antenna /
ic_product_private_window so the private NTP renders the Leo
(Nala) icons via resource_overlay; tint the inner icon layer to
primitive_private_window_60 in IncognitoNewTabPageView so the
designed purple still wins on the fixed-dark surface.
- Remove Brave-local primitive_private_window_5/10/20/60/80/90 from
brave_colors.xml; references now resolve through Leo's primitive
scale (same hex for _60/80/90; slight neutral shift for _5/10/20).
- Remove the runtime setBackgroundColor on the scroll view that was
masking the gradient drawable defined in the layout XML.
- Switch the private-tab logo to ic_social_brave_release_favicon_-
fullheight_color (Leo) and size in dp (42 phone, 56 tablet) to
match Figma and to stop scaling with accessibility font size.
- Resize circle drawable to 32x32 (was 32x33), constrain inner icon
via new_tab_page_incognito_icon_inner_size (20dp / 24dp tablet),
and grow circle to 48dp on tablets.
- Introduce per-form-factor style aliases (IncognitoNtpTitle /
SectionTitle / SectionDescription / Cta) under values/ +
values-sw600dp/ so phones and tablets land on the right Leo
typography ramp without per-TextView attributes.
- Delete the now-dead ntp_bg_incognito and incognito_modern_-
primary_color color entries.
