Lateania: rich character sheet, class portraits, and roster tables

[hardlygospel]

Thanks for late.sh, @mpiorowski! This makes Lateania's UI feel a lot more alive — inspired by the dense, visual character/roster panels in team-management TUIs.

What

• Full-width character sheet. The Character panel (c) now expands into a dashboard when the terminal has room (≥72×14): an accent-tinted class portrait, the six ability scores as dot ratings (the class's primary score highlighted), HP/resource as filled meters, combat numbers, the passive trait, earned titles, and an XP meter. On cramped terminals it falls back to the existing narrow side panel, so nothing regresses for small windows.
• Class portraits. Each of the five classes gets an ASCII portrait bust, tinted by a per-class accent colour and captioned with a class emblem.
• Roster tables. The room Foes and Adventurers lists and the Follow (party) panel now render as aligned rows: a name column plus a small HP meter tinted by remaining health. (The Follow panel previously ignored the occupant HP it already had in hand.)

All rendering stays lock-free and snapshot-only — no changes to the service, world, or persistence. Reuses the existing build_composer-style helpers and the snapshot's existing data; no new fields on PlayerView.

Tests

Added unit tests for the pure helpers (dot-rating scaling, meter fill/clamp, unicode-aware name fit/ellipsize).

cargo test -p late-ssh --lib door::lateania   # passing, incl. new ui tests
cargo clippy -p late-ssh --lib                # clean
cargo fmt --check                             # clean

Updated door/lateania/CONTEXT.md to describe the new sheet/roster rendering.
