Description

Long names without spaces now wrap inside the notifications drop instead of being cut off. Activity texts fill their placeholders in one pass, so a placeholder inside a file name is no longer replaced.

Related Issue

• Fixes Long names overflow the notifications drop #3890
• Fixes File names with placeholders like {sharee} change the text in the Activities panel #3891

How Has This Been Tested?

• test environment: unit tests (Vitest), browser tests (Playwright) against a local OpenCloud
• test case 1: unit: an activity keeps placeholders inside inserted names
• test case 2: browser: long names wrap inside the notifications drop (desktop and mobile); a file named with {sharee} keeps its name in the share activity, normal activities unchanged
