* feat(servers): magic string invites and duplicate-aware labels
Add psysonic1- share payloads (URL, Subsonic credentials, optional server
name). Login and add-server forms decode on input and keep magic field
below standard fields. Navidrome User Management generates strings after
PUT password updates where required. Resolve duplicate display names as
username@host in chrome, settings, and login.
* feat(servers): tighten magic-string import and admin share flow
After a decoded magic string, username is read-only and the password field
shows a fixed-length mask so length is not inferred. Password reveal stays
disabled until saved-server quick connect (login) or reopening the add-
server form. Navidrome admin share UI persists the password via API before
copy and adds a plaintext-handling disclaimer. Locales updated.
* feat(settings): save new Navidrome user and copy magic string
Add a non-admin "Save and get magic string" flow: create the user, assign
libraries when needed, then encode credentials to the clipboard. Reuse
the plaintext-handling disclaimer without the password-update hint meant
for edits. Strings added for all locales.
* fix(settings): tighten Navidrome add-user validation and submit feedback
Require username, display name, and a non-empty password (trimmed) for new
users; gate Save and “save and get magic string” on explicit checks with
toast feedback. Show red borders only after a failed submit, and clear
them when the user fills the fields. When editing, keep an empty password
as “unchanged” and validate identity fields with a dedicated message.
Strings: userMgmtValidationMissingIdentity across locales.
