Why: the change-password modal rendered loose password inputs outside any
<form> with no autocomplete or username association (browser password-form
warnings; Enter did not submit), and its 401 handling collapsed every
cause into "wrong current password". SettingInput masked ALL free-text
config values as password fields.
Evidence: vitest 24 files / 116 tests incl. new settingInputAttrs matrix;
knip and tsc -b && vite build pass; e2e changepw-form spec (driven by the
dev-repo e2e.sh plain phase) covers form submit via Enter, autocomplete
trio, readonly username and the classified error copy.
Impact: ChangePasswordModal uses form onSubmit, htmlFor/id association,
username/current-password/new-password autocomplete and reuses
humanChangePasswordError; SettingInput renders text inputs unless the
field is secret.
