feat(entry): normalise Name/QTH/Comment/Note case, upper-case the Recent QSOs search

One station reaches the log SHOUTED by QRZ, lower-cased by a hurried
operator and in whatever case an imported ADIF carried, so the same name
appears three ways across a log. Name and QTH are now title-cased word by
word; Comment and Note only get a capital first letter, because the rest
routinely holds callsigns and modes ("TNX QSO F5ABC, FT8 59") that
lower-casing would destroy.

Normalised on blur, never per keystroke — rewriting the value mid-word
fights the typist (the controlled-input trap in CLAUDE.md). Applied in
both entry layouts and in the QSO editor, since leaving the editor alone
would just reintroduce the mess on the first correction.

The Recent QSOs box only ever searches callsigns, so it upper-cases as
you type and carries an inline clear button.
