style: normalizare CRLF -> LF pentru scripturile shell

Doar line endings, zero modificari de continut (verificat cu
git diff --ignore-cr-at-eol: fara diferente ramase pe aceste fisiere).

Fisierele aveau CRLF comis efectiv in repo, nu doar in working tree.
Sunt scripturi care ruleaza pe Linux (migrarea Oracle, LXC 171 claude-agent),
iar deployate direct din working tree bash le refuza cu
"$'\r': command not found" - exact capcana pe care .gitattributes (comis in
9475842) o previne de acum inainte pentru fisierele noi.

Nu sunt incluse fisierele .md/.sql din roa-windows-setup: acelea au
modificari reale de continut, in curs, si apartin altui commit.
