frontend: NamespacesAutocomplete: Fix react-hooks/exhaustive-deps — add missing deps to useDefaultNamespaceFallback

[rajeshsingh241]

Add allClustersConfigs as a genuine missing dependency to the
useEffect in useDefaultNamespaceFallback hook.

selectedNamespaces and dispatch are intentionally kept out of
the dependency array — adding selectedNamespaces causes infinite
re-renders when the user clears the namespace filter, and dispatch
is stable across renders (Redux guarantee). The eslint suppression
is kept with an inline comment explaining this.

Part of #5183

Thanks for this PR.

A few of the commits don't quite follow the project guidelines. We use Linux kernel style for git commits — have a look at the contributing guide and previous commits with git log.

Commits that need attention

• frontend: NamespacesAutocomplete: fix prettier formatting — Description must start with a capital letter — e.g. frontend: HomeButton: Fix the button not frontend: HomeButton: fix the button.

Commit guidelines

• Use atomic commits focused on a single change.
• Use the title format <area>: <Description of changes> — description must start with a capital letter.
• Keep the title under 72 characters (soft requirement).
• Explain the intention and why the change is needed.
• Make commit titles meaningful and describe what changed.
• Do not add code that a later commit rewrites; squash or reorder commits instead.
• Do not include Fixes #NN in commit messages.

Good examples:

• frontend: HomeButton: Fix so it navigates to home
• backend: config: Add enable-dynamic-clusters flag

Thanks for the review @illume! I've squashed the commits into one and fixed the dependency array-- selectedNamespaces and dispatch are now intentionally omitted with comments explaining why. Please take another look.
