feat(Console): Add quick setup feature

[vignesh-manel]

Adds an interactive wizard to the console that lets users bootstrap Polaris from scratch — creating principal roles, principals, catalogs, namespaces, and catalog roles in one guided flow using either preset examples or user-provided YAML.

Features & Changes

• Two setup modes — choose a ready-made preset (Local File, AWS S3, Azure ADLS, Google Cloud) or paste/upload a custom YAML config in the same format as polaris setup apply
• Guided preset flow — parameterized inputs (catalog name, storage location, role ARN, etc.) with required-field validation before proceeding
• YAML mode with live validation — 300ms debounce parse with inline feedback; validates structure, required fields (storage_type, default_base_location), and storage type values
• Step preview — review all planned actions before applying; existing entities are automatically skipped (409 treated as success)
• Live progress view — each step updates in real-time as it executes; failed steps are clearly flagged while remaining steps continue where possible
• Credential display — generated principal credentials are shown with copy buttons at the end of the flow; not persisted anywhere
• Error resilience — catalog sub-steps are skipped gracefully if catalog creation fails; a fatal API error (e.g. 403 on list) halts remaining steps cleanly with a summary

Limitations / Known Issues

• No partial resume — if the wizard is closed mid-execution, there is no way to resume; re-running from the start is safe (idempotent) but will skip already-created entities
• YAML validation is structural only — the wizard validates shape and required fields but does not verify that referenced roles, catalogs, or principals actually exist in Polaris before running
• Preset YAML view is read-only — the generated config from a preset cannot be edited in the wizard before applying; switch to YAML mode for full control
• Credentials shown once — generated client secrets are displayed only in the final step and are not recoverable after closing the wizard
• No teardown support — the wizard only creates entities; there is no corresponding flow to delete or clean up the resources it provisioned
