News block field group is titled "Modal Block"

[Herm71]

Found while writing docblocks for src/Blocks/ (#121).

Problem

The News block's ACF field group is titled "Modal Block":

protected function get_title(): string {
	return esc_html__( 'Modal Block', 'ucsc' );
}

That string is what an editor sees as the field group heading in the block sidebar when they select a News block. There is no modal anywhere in this plugin — grep -ri modal over the repo returns this line and nothing else — so it reads as a copy-paste leftover rather than a deliberate name.

Introduced in 7bb59e0 ("Register News block (#30) (#32)"), the commit that first added the block, so it has been wrong since the block shipped.

For comparison, every other block titles its group after itself:

block	group title
Featured News	Featured Stories
Magazine	UCSC Magazine
Media Coverage	Media Coverage
Photo of the Week	UCSC Photo of the Week Block
Post Header	Post Header
Press Inquiries	Press Inquiries
Related Stories	Related Stories
News	Modal Block

Why it wasn't fixed in #121

That PR is documentation-only and verified as such by token comparison. Changing this string is a user-visible content change and wanted its own decision.

Fix

Rename to something that describes the block — "News" or "News Block", matching the pattern above.

This is safe to change. The group title is cosmetic; the group key comes from get_key() → News_Block::NAME (news_query_block) and is untouched, so no saved field data is affected and no migration is needed.

Worth deciding the exact wording with whoever supports editors, since it appears in the editing UI.

Acceptance

• Field group title describes the News block
• News_Block::NAME / get_key() unchanged
• Existing News blocks still render with their saved field values intact
• The stale note in the get_title() docblock referencing this issue is removed
