Show the active chain on share cards

[sedge-bot]

Summary

• pass the active EVM chain short name into lock success and vault share cards
• size the share-card chain badge to fit the chain label instead of hardcoding Base
• preserve the existing card layout for current Base locks while making other chains accurate

Verification

• corepack pnpm --filter app test
• corepack pnpm --filter app build
• git diff --check -- packages/app/src/app/create/page.tsx packages/app/src/app/vaults/page.tsx packages/app/src/components/ShareCard.tsx
