[PATCH proxmox_login_manager 1/1] cleanup: replace use of deprecated props and fix dart analyze issues

[Shan Shaji <s.shaji@proxmox.com>]

`value` property is deprecated in favor of `initialValue` starting from
v3.35 [0]. Replaced the use of `value` prop with `initialValue`. Additionaly,
removed the library name, as that is not necessary anymore [1].

[1] - https://dart.dev/tools/linter-rules/unnecessary_library_name
