fix: apply formatValue before truncateDisplay for correct value rendering}
- Bump version from 2026.4.426 to 2026.4.427 in package.json and README.md
- Swap call order from formatValue(truncateDisplay(value)) to
truncateDisplay(formatValue(value)) across all key type components
- Affected Angular templates: key-hash, key-list, key-set, key-stream,
key-string, key-zset
- Affected React components: KeyHash, KeyList, KeySet, KeyStream,
KeyString, KeyZset
- Ensures values are formatted before truncation so formatting operates
on the full value rather than on already-truncated output
