feat: support for ollama prerendered agent block list and disable api key field

[justserdar]

The PR is a WIP the last weeks including back and forth conversations with hummus, it adds the missing prerendered Ollama list in the AI agent block and conditionally renders the api key field for only the base models.

Description

1. Disabled the guard that stops client-side ollama store initialisation.
2. Ollama models are added to the list when the env is correct, setting the right url of the consumers ollama instance is required.
3. 'ollamais required as ollama api key, this is handled in the current ollama provider. Changed value fromemptytoollama`.
4. Conditionally disabled the API key field for the local Ollama list.
5. Conditionally disable api key check in the api/prodivers.ts endpoint.

Important:
Point 2 needs correct env passthrough via OLLAMA_URL.
Point 4 needs work because on page refresh the api key field is still being rendered while it wasn't before the page reload.
Point 5 need work just for ollama in self hosted situations, so we might need to add another check like isHosted, suggestion: isSelfHosted and isSelfHostedModel to make handling these situations more elegantly.

PR Summary

Enhances Ollama integration by modifying client-side initialization and API key handling in the agent block interface. Changes primarily focus on improved local model support and conditional UI rendering.

• Modified apps/sim/providers/ollama/index.ts to remove client-side initialization guard and standardize API key to 'ollama'
• Updated apps/sim/blocks/blocks/agent.ts to conditionally hide API key field for local Ollama models
• Issue: Page refresh causes API key field to incorrectly reappear for local models
• Pending: API provider endpoint needs additional isSelfHosted check for Ollama-specific handling

style: Avoid using console.log for debugging in production code. Use the logger instead for consistency.

Suggested change

	console.log('response', response)
	logger.debug('response', response)

style: Store state accessed twice - consider memoizing or moving to a constant to avoid potential inconsistencies between the two calls.
