feat: create pages page

[martian56]

This pull request introduces significant enhancements to the API, focusing on notifications, issue subscriptions, and page management. It adds new endpoints for managing notification states (such as snoozing, archiving, and unread counts), introduces subscription endpoints for issues, and refactors the page handler to support more flexible queries and better error handling. Additionally, it updates several Go module dependencies.

Notification API Enhancements:

• Added new endpoints to the NotificationHandler for snoozing (Snooze/Unsnooze), archiving (Archive/Unarchive), and marking notifications as unread (MarkUnread). Also, added an endpoint to get unread counts with mention breakdown (UnreadCount). The List endpoint now supports filtering by unread, mentions, and archived state. [1] [2] [3]

Issue Subscription API:

• Introduced endpoints in IssueHandler to allow users to check if they are subscribed to an issue, subscribe, and unsubscribe. These endpoints provide better control for users to manage their issue notifications.

Page API Improvements:

• Refactored PageHandler to support more flexible listing with filters (such as archived, parent, search, and ownership), added a new endpoint for listing child pages, and centralized error handling for consistent API responses.

Dependency Updates:

• Updated several dependencies in api/go.mod, including upgrades to golang.org/x/crypto, golang.org/x/net, golang.org/x/tools, and others for improved security and compatibility. [1] [2]

Note

Medium Risk
Moderate risk because it introduces new persistence models and API endpoints (issue subscriptions, notification snooze/archive, page versions/favorites) and changes core notification fan-out behavior; correctness depends on DB schema/migrations and preference/subscriber wiring.

Overview
Adds a full issue-following + notification fan-out pipeline: introduces issue_subscribers with subscribe/unsubscribe endpoints, auto-subscribes assignees/commenters/mentions, and emits in-app notifications for assignments, mentions, comments, state changes, and other field changes (with structured message payloads and cleanup on issue delete).

Expands the notifications inbox API to support unread counts (with mention breakdown), filtering (unread/mentions/archived), and per-notification actions (mark unread, archive/unarchive, snooze/unsnooze), backed by new store methods and new Notification fields (sender, snoozed_till).

Significantly upgrades pages: adds richer Page fields, server-side list filtering, hierarchical navigation (parent_id + children listing), owner-only meta updates vs content autosave, lock/archive/delete semantics, duplication, version history/restore via page_versions, and page favorites via user_favorites.

UI updates wire these capabilities: adds a polling header NotificationBell, revamps NotificationsPage with tabs (All/Mentions/Archived) and actions (read/unread, archive, snooze, open issue) using the structured payload renderer, and adds an issue SubscribeButton. Also bumps Go x/* dependencies and increments UI version to 0.7.0.
