ci(frontend): disable chromatic for this month (#11994)

### Changes 🏗️

- we react the max snapshots quota and don't wanna upgrade
- make it run (when re-enabled) on `src/components` changes only to
reduce snapshots

### Checklist 📋

#### For code changes:
- [x] I have clearly listed my changes in the PR description
- [x] I have made a test plan
- [x] I have tested my changes according to the test plan:
  - [x] CI hope for the best

+## Text Encoder
+
+### What it is
+Encodes a string by converting special characters into escape sequences
+
+### How it works
+<!-- MANUAL: how_it_works -->
+The Text Encoder takes the input string and applies Python's `unicode_escape` encoding (equivalent to `codecs.encode(text, "unicode_escape").decode("utf-8")`) to transform special characters like newlines, tabs, and backslashes into their escaped forms.
+
+The block relies on the input schema to ensure the value is a string; non-string inputs are rejected by validation, and any encoding failures surface as block errors. Non-ASCII characters are emitted as `\uXXXX` sequences, which is useful for ASCII-only payloads.
