feat(web): use the OpenCloud brand colors for the primary color role

[AlexAndBear]

Description

Applies the OpenCloud brand colors to the primary color role of the default OpenCloud theme, in both the light and the dark theme:

Role	Light (before)	Dark (before)	Light & dark (after)
primary	#00677f	#5cd5fb	#e2baff
onPrimary	#ffffff	#003543	#20434f

The primary role is used for the call-to-action ("New" button / FAB). The web counterpart that removes the gradient from the FAB and moves the checkboxes to the secondary role is opencloud-eu/web#3521.

Motivation and Context

The CTA should use the OpenCloud brand colors instead of the generic petrol/cyan tones, as requested in the issue above.

How Has This Been Tested?

• test environment: local docker setup of the web repo using opencloudeu/opencloud:dev built via make dev-docker
• test case 1: the "New" button in the sidebar (desktop) uses #e2baff with #20434f text in the light and dark theme
• test case 2: the FAB on mobile resolutions uses the same colors

Screenshots (if appropriate):
