fix(client): resolve all gdlint warnings — zero warnings policy

Fix 354 gdlint warnings across 65 files: 194 class-definitions-order
(reorder declarations), 138 max-line-length (split long lines),
22 code issues (unused args, no-else-return, naming). Update .gdlintrc
to exclude addons/ and raise max-public-methods for test files.
No logic changes — declaration order, whitespace, and naming only.

Ticket: #783
