new central AI config

[Mbeaulne]

Description

Replaces the hardcoded aiAssistantConfig.json and single-token proxy model with a unified bring-your-own-provider configuration (AiProviderConfig) that is stored in localStorage under tangle.aiProvider.config and shared across all AI features (AI assistant, component search reranking, and component description generation).

Key changes:

• Introduces src/types/aiProvider.ts with the shared AiProviderConfig interface (apiBase, apiKey, model), all of which are now optional except apiBase.
• Removes src/config/aiAssistantConfig.json, src/agent/aiTokenStore.ts, and src/hooks/useComponentSearchSettings.ts. Their responsibilities are absorbed by the new useAiProviderSettings hook (tangle.aiProvider.config storage key) which falls back to the legacy tangle.componentSearchV2.config key and migrates the old thinkingModel field.
• isConfigured now only requires apiBase to be non-empty; apiKey and model are optional to support proxy setups that own authentication and model selection.
• ProxyClient.ensureConfigured now accepts AiProviderConfig instead of a raw token string. When apiKey is blank, the Authorization header is stripped from outgoing requests via a custom fetch wrapper.
• All agents (tangleDispatcher, debugAssistant, generalHelp, pipelineArchitect, pipelineRepair) now receive model configuration via getAgentModelConfig(session.aiConfig) spread into the agent constructor, replacing the requireOrchestratorModel / requireSubagentModel calls.
• AgentSession carries aiConfig so every agent and tool has access to the provider config without touching module-global state.
• The AiTokenSetup component is replaced by AiProviderSetup, which links to the settings page instead of prompting for a raw token.
• The Settings sidebar "AI Configuration" entry is now shown when either the component-search-v2 or ai-assistant feature flag is enabled.
• Validation in AgentSettings and naturalLanguageComponentSearchService is relaxed to require only apiBase; API requests omit the Authorization header and model field when those values are blank.
• Embedding model and skills base URL are now derived from constants rather than the deleted config file.

Test Instructions

1. Open Settings → AI Configuration and verify the page is accessible when either component-search-v2 or ai-assistant is enabled.
2. Enter only an API base URL (leave API key and model blank) and click Save — confirm it saves successfully and isConfigured becomes true.
3. Open the AI assistant panel and confirm it shows the AiProviderSetup prompt (link to settings) when no provider is configured, and loads the chat interface once configured.
4. Verify AI component search reranking and description generation work with a proxy that does not require an API key or explicit model selection.
5. Confirm that existing localStorage data under tangle.componentSearchV2.config is read correctly as a fallback and that thinkingModel is migrated to model.

Additional Comments

The tangle.componentSearchV2.config key is still read as a fallback but is removed from localStorage on the next clear() call. No explicit one-time migration is performed; the fallback read handles existing users transparently.
