fix: apply the row truncation Screen Option to snippet names (3.10.2)

[TallblokeUK]

Retarget of #495 onto the release branch. Same commit, cherry-picked, so it applies without dragging in unrelated core-beta changes to the test files.

Reported on Discord against 3.10.1: the Truncate long snippet names and descriptions Screen Option only affects the Description column. Snippet names stay truncated whether the option is on or off, which makes long names hard to tell apart. If the Description column is hidden, toggling the option appears to do nothing at all.

The reporter identified the cause themselves, and they were right.

Cause

The option toggles a truncate-row-values class on the list table, but only the description rule was scoped to it:

td.column-name > .snippet-name { … }                                    // unconditional
&.truncate-row-values td.column-desc .snippet-description-content { … } // scoped

So names were always clipped to min(15rem, 30vw) regardless of the setting. The class itself toggles correctly — it simply never governed the Name column.

Fix

Scope the name rule to the same class, so the option governs both values as its label promises.

Testing

Measured on the same row, with a deliberately long (88 character) snippet name:

	before	after
option on	max-inline-size: 240px, clipped	max-inline-size: 240px, clipped
option off	max-inline-size: 240px, clipped	max-inline-size: none, full name shown

With the option off the name now wraps and is fully readable; the row grows by one line, which is the same behaviour the Description column already has. With it on, nothing changes. Verified by toggling the Screen Option through the UI rather than by forcing the class, on a clean WordPress 7.1 install with the plugin installed from a built zip. stylelint clean.

Note

This covers the table view only. The card/grid view never receives the truncate-row-values class, and its truncation is structural — a long name would otherwise push the header icons out of the card. That looks deliberate, so it is left alone here.
