fix(nui): reset styled text with ~s~

[Gamzky]

Description

Fix ~s~ so it closes colored text in NUI notifications (it was removed before parsing, so colors never reset).

---

Motivation

Strings like ~b~$500~s~ should match GTA/ESX markup. They stayed the wrong color because ~s~ was stripped too early.

---

Implementation Details

Stop stripping ~s~ before the color pass. Strip any leftover ~s~ only after replaceColors runs on title and message.

---

Usage Example

ESX.ShowNotification('Paid ~b~$500~s~ deposit.', 'info', 5000)

After:
