chore: improve tests

[moul]

• chore: Ensure consistency in txtar test (found in issue feat: introduce personal realms, add r/manfred/home #1138).
• chore: Temporarily disable malfunctioning tests (discovered by Jae, who manually executed make test locally without a gnoland node running).

@gfanton, could you assist in integrating the new gnoland/pkg/integration package you created into gno.land/cmd/gnoweb/*_test.go? Please remove my t.Skip() as well.

Additionally, it seems that the CI was not testing gnoweb or running a gnoland node to ensure its functionality. We should review the configuration to determine if it is adequate or requires improvement.
