chore: resolve WIP after merging internal/development

- .gitignore: keep api/uploads ignore and copyright_source_listing.pdf path

- auth: keep COS avatar upload URL; delete prior COS object when applying preset

- i18n: regenerate resources.ts (includes profile tapAwayToClose)

- Avatar/COS tests and personal-info remain from prior local work
