fix: react-hooks/exhaustive-deps in frontend directory

[ta1m1kam]

Overview

This PR fixes ESLint errors across the frontend codebase, with a focus on React hooks dependencies and circular
reference issues. The main refactor targets the useNormalizedConversation hook, while also updating ESLint
configuration for better code quality.

Problems Addressed

1. Circular dependencies in hooks: The useNormalizedConversation hook had complex circular dependencies between
   callbacks
2. Missing React hooks dependencies: Multiple useCallback and useEffect hooks had incorrect dependency arrays
3. ESLint configuration: Missing explicit rule for react-hooks/exhaustive-deps
4. Code maintainability: Unnecessary use of refs to work around circular dependencies

Changes

1. ESLint Configuration Updates

• Added explicit react-hooks/exhaustive-deps rule configuration in .eslintrc.json
• Set the rule to "error" level to catch dependency issues during development

2. Major Refactor: useNormalizedConversation Hook

• Eliminated circular dependencies: Moved scheduleReconnect as a local function inside establishSSEConnection
• Removed unnecessary refs: Deleted establishSSEConnectionRef and related ref management code
• Consolidated logic: Merged createSSEConnection functionality into a single callback
• Fixed all dependency warnings: Properly declared all dependencies in useCallback hooks

3. Minor Fixes Across Components

• Updated dependency arrays in various components to satisfy ESLint rules
• Added missing dependencies where needed
• Used ESLint disable comments sparingly where circular dependencies were intentional
