Problem: SystemStackError: stack level too deep occurred when rendering
messages with indented content (4+ spaces) for WhatsApp, Instagram, and
Facebook channels.
Root Cause: CommonMarker::Renderer#code_block contains a self-recursive
placeholder that must be overridden:
```
def code_block(node)
code_block(node) # calls itself infinitely
end
```
WhatsAppRenderer and InstagramRenderer were missing this override,
causing infinite recursion when markdown with 4-space indentation
(interpreted as code blocks) was rendered.
Fix: Added code_block method to both renderers that outputs the node
content as plain text:
```
def code_block(node)
out(node.string_content)
end
```

## Description
This PR fixes a UX bug in the Custom Attributes settings page where
switching tabs becomes impossible when the currently selected tab has no
attributes.
Closes#13120
### The Problem
When viewing the Custom Attributes settings page, if one tab (e.g.,
Conversation) has no attributes, users could not switch to the other tab
(e.g., Contact) which might have attributes.
### Root Cause
The `SettingsLayout` component receives `no-records-found` prop which,
when true, hides the entire body content including the TabBar. Since the
TabBar was inside the body slot, it would be hidden whenever the current
tab had no attributes, preventing users from switching tabs.
### The Fix
- Removed the `no-records-found` and `no-records-message` props from
`SettingsLayout`
- Moved the empty state message inline within the body, displayed below
the TabBar
- The TabBar is now always visible regardless of whether there are
attributes in the selected tab
### Key Changes
- Modified `Index.vue` to handle empty state inline while keeping TabBar
accessible
## Type of change
- [X] Bug fix (non-breaking change which fixes an issue)
## How Has This Been Tested?
1. Navigate to Settings > Custom Attributes
2. Ensure only one tab (e.g., Contact) has custom attributes
3. Switch to the empty tab (e.g., Conversation)
4. Verify the TabBar remains visible and the empty state message is
shown
5. Switch back to the tab with attributes
6. Verify attributes are displayed correctly
7. Repeat with both tabs empty and both tabs with attributes
Previously, attachments relied only on blob_id, which made it possible
to attach blobs across accounts by enumerating IDs. We now require both
blob_id and blob_key, add cross-account validation to prevent blob
reuse, and centralize the logic in a shared BlobOwnershipValidation
concern.
It also fixes a frontend bug where mixed-type action params (number +
string) were incorrectly dropped, causing attachment uploads to fail.
