Enhance AI Agent Profile Interaction

This commit introduces several enhancements to how AI agent profiles are displayed and interacted with:

**Profile Display:**
- **AI Account Distinction:** Profile pages now differentiate between regular user accounts and AI agent accounts.
    - AI agent profiles will not display the "Agents" tab in their profile.
    - The profile header height is adjusted for AI accounts.
- **Navigation Parameter:** An `isAiAccount` boolean parameter is added to the `AccountProfile` navigation route to indicate if the profile being viewed belongs to an AI.

**Interaction & Navigation:**
- **Avatar Click Navigation:**
    - Clicking an AI agent's avatar in various lists (Hot Agents, My Agents, User Agents Row, User Agents List) now navigates to the agent's dedicated profile page.
    - When navigating to an agent's profile from an agent list, `isAiAccount` is set to `true`.
- **Chat Initiation:** Clicking the chat button on AI agent cards in the "Agent" tab (both Hot and My Agents) now correctly initiates a chat with the respective AI.
- **ViewModel Updates:**
    - `AgentViewModel`, `MineAgentViewModel`, and `HotAgentViewModel` now include a `goToProfile` function to handle navigation to agent profiles, correctly passing the `isAiAccount` flag.

**Code Refinements:**
- Click handlers for agent avatars and chat buttons are now wrapped with `DebounceUtils.simpleDebounceClick` to prevent multiple rapid clicks.
- The `UserContentPageIndicator` now conditionally hides the "Agent" tab based on the `isAiAccount` status.
- `UserAgentsRow` and `UserAgentsList` now accept an `onAvatarClick` callback for navigating to agent profiles.
- `AgentItem` (used in `UserAgentsRow`) and `UserAgentCard` (used in `UserAgentsList`) now handle avatar clicks.
- The general `Agent` composable (used in `AiPostComposable`) now also supports an `onAvatarClick` callback.
