fix(frontend): add min-width-0 to ContentCard to prevent overflow (#12060)

### Changes 🏗️

Added `min-w-0` class to the ContentCard component in the ToolAccordion
to prevent content overflow issues. This CSS fix ensures that the card
properly respects its container width constraints and allows text
truncation to work correctly when content is too wide.

<h2>Greptile Overview</h2>

<details><summary><h3>Greptile Summary</h3></summary>

Added `min-w-0` class to `ContentCard` component to fix text truncation
overflow in grid layouts. This is a standard CSS fix that allows grid
items to shrink below their content size, enabling `truncate` classes on
child elements (`ContentCardTitle`, `ContentCardSubtitle`) to work
correctly. The fix follows the same pattern already used in
`ContentCardHeader` (line 54) and `ToolAccordion` (line 54).

<details><summary><h3>Confidence Score: 5/5</h3></summary>

- Safe to merge with no risk
- Single-line CSS fix that addresses a well-known flexbox/grid layout
issue. The change follows existing patterns in the codebase and is
thoroughly tested. No logic changes, no breaking changes, no side
effects.
- No files require special attention
