Login Qr code text is not readable in the lockscreen when using a light theme

[Marco Trevisan (Treviño)]

[ Impact ]

When using the light theme the qr code dialog in the lockscreen is not visible: https://imgur.com/USKxSbl.png

[ Test case ]

0. Using the default theme variant (any light color)
1. Configure authd to use a broker that supports web authentication
2. Lock the screen
3. Try to unlock the screen using a QrCode for authenticating

[ Regression potential ]

Lockscreen dialog is not properly visible in GDM (at login phase), or it may have wrong or not visible colors

Note that authd is not yet available in noble, thus wrong behaviors when logging in with it can't be considered really "regressions".

Oracular and Jammy, but missing Noble?

[Marco Trevisan (Treviño) (3v1n0)]

Oh, actually was just Noble, but my brain is not yet used to do last_lts=${last_lts/jammy/noble} :)
