ui(tokens): migrate border-kodo-steel to border-border (86 files, 269 instances)
Replace legacy hardcoded border-kodo-steel (RGB 59,69,84, theme-unaware)
with semantic border-border token across 86 user-facing components.
Covers UI primitives (checkbox, badge, modal, table, textarea, alert,
radio-group, avatar), all modals, settings views, social features,
playlist views, inventory, chat, commerce, and cloud file browser.
Only story/test files retain the legacy token.
