fix: prevent -- signature delimiter rendering as \ in bubble (#14134)
# Pull Request Template

## Description

Fixes
https://linear.app/chatwoot/issue/CW-6903/signature-delimiter-renders-as-h2-when-using-enter-line-before

**1**. Fixes an issue where the signature delimiter `--` gets parsed as
an H2 when using **Enter** (new paragraph) before or after it, causing
it to render as a bold `\` in the message bubble.

* Ensures `--` renders as plain text
* Aligns renderer with parser behavior (both disable `lheading`)
* Prevents stray `\` from appearing as heading text

**2**. Also fixes a related editor issue where toggling signature
**off** leaves behind a stray `\` or `-- \`.

* Strips blank paragraph markers (`\`) and dangling hard breaks
(`\<newline>`) from ProseMirror serializer
* Applied in both `appendSignature` and `removeSignature`
* Replaces `trimEnd()` with shared helpers (`trimTrailingBlanks` /
`stripTrailingBlankMarkers`)

3. Toggle signature off

2. Send a message using Enter between lines
3. Verify `--` renders correctly (no H2, no bold `\`)
