feat(tray): show coding-plan usage for Kimi / Zhipu / MiniMax

dc04165f surfaced tray usage badges for Claude/Codex/Gemini official
OAuth only. Chinese coding-plan providers already expose 5h + weekly
windows through coding_plan::get_coding_plan_quota, but two gaps kept
the tray from rendering them.

- format_script_summary read only data.first(), truncating the tier-
  flattened UsageResult to a single window. Detect plan_name matching
  TIER_FIVE_HOUR / TIER_WEEKLY_LIMIT and emit the "🟢 h12% w80%" layout
  used by format_subscription_summary; worst utilization drives the
  emoji. Copilot / balance / custom scripts keep the legacy single-
  bucket output via fallback.

- usage_script previously required manual activation through
  UsageScriptModal. Auto-inject meta.usage_script on Claude provider
  creation when ANTHROPIC_BASE_URL matches a known coding plan, so the
  tray lights up without the user opening the modal. Does not overwrite
  existing usage_script on update.

Extract the URL route table out of UsageScriptModal into a shared
codingPlanProviders module so the modal, the creation hook, and the
Rust coding_plan::detect_provider mirror all agree on one list.
Add TIER_WEEKLY_LIMIT alongside TIER_FIVE_HOUR and a createUsageScript()
factory to collapse the duplicated default fields across four call
sites and drop the remaining stringly-typed tier names.
