feat(ui): entity-anchored dialogue log with keyboard selection

Log entries store entity IDs and resolve display names at render
time from _entity_display lookup — enables retroactive name update
when player learns an NPC's real name. Color index from server
replaces name-hash coloring for stable NPC colors.

Dialogue options: switched RichTextLabel to Label (fixes stacking
bug), added 1/2/3 number key selection, numbered option labels.

Interaction list: added background panel, mouse hover highlighting,
click-to-interact, pointing hand cursor.
