Lateania: improve the character sheet (creation + in-game)

[hardlygospel]

Thanks @mpiorowski! A pass on the Lateania character sheet to make it dense, rated, and colour-coded — both on the creation screen and in-game.

What changed

• Star ratings. Each ability score shows a 5-star rating (replacing the old dot bars), and the section headers carry one too — Attributes ★★★☆☆, Combat, Trades. The class's primary score glows in the class accent.
• Tier-coloured values. Every score's number is coloured by how strong it is: faint for a weak stat, amber for middling, green for strong — so strengths and weaknesses pop at a glance.
• Offence / defence split. Combat now reads attack as offence (green) and armour as defence (blue).
• Creation matches the sheet. The rolled-fate block on the class-select screen and the compact character panel render from the same attribute_lines helper as the full sheet, so a freshly-rolled hero reads exactly like the finished one — as you cursor through classes the primary score re-highlights in that class's accent.

Notes

Happy to tune the star mapping, tier thresholds, or colours to taste. The rating colours reuse existing theme::* values.

Tests
