fix(ui): align the transaction detail sheet with the app's sheet conv…

…entions

Why:

• The sheet was the only one with an icon at header right where every sibling puts text, and the only one whose hero glyph was a circle while the identical category glyph is a rounded square in the list rows. The delete control rendered as an empty Text to screen readers, naming the action for nobody, and the title was hardcoded English.

What:

• Delete reads as text using the existing common.delete label, the hero glyph takes the same radius as the list rows, both header controls carry a proper accessibility role, and the title is translated across the five complete locales. The list renderers are untouched.
