Jared Vititoe 89a685a502 Integrate web_template design system and fix security/quality issues ...

Security fixes:
- Add HTTP method validation to delete_comment.php (block CSRF via GET)
- Remove $_GET fallback in comment deletion (was CSRF bypass vector)
- Guard session_start() with session_status() check across API files
- Escape json_encode() data attributes with htmlspecialchars in views
- Escape inline APP_TIMEZONE config values in DashboardView/TicketView
- Validate timezone param against DateTimeZone::listIdentifiers() in index.php
- Remove Database::escape() (was using real_escape_string, not safe)
- Fix AttachmentModel hardcoded connection; inject via constructor

Backend fixes:
- Fix CommentModel bind_param type for ticket_id (s→i)
- Fix buildCommentThread orphan parent guard
- Fix StatsModel JOIN→LEFT JOIN so unassigned tickets aren't excluded
- Add ticket ID validation in BulkOperationsModel before implode()
- Add duplicate key retry in TicketModel::createTicket() for race conditions
- Wrap SavedFiltersModel default filter changes in transactions
- Add null result guards in WorkflowModel query methods

Frontend JS:
- Rewrite toast.js as lt.toast shim (base.js dependency)
- Delegate escapeHtml() to lt.escHtml()
- Rewrite keyboard-shortcuts.js using lt.keys.on()
- Migrate settings.js to lt.api.* and lt.modal.open/close()
- Migrate advanced-search.js to lt.api.* and lt.modal.open/close()
- Migrate dashboard.js fetch calls to lt.api.*; update all dynamic
  modals (bulk ops, quick actions, confirm/input) to lt-modal structure
- Migrate ticket.js fetchMentionUsers to lt.api.get()
- Remove console.log/error/warn calls from JS files

Views:
- Add /web_template/base.css and base.js to all 10 view files
- Call lt.keys.initDefaults() in DashboardView, TicketView, admin views
- Migrate all modal HTML from settings-modal/settings-content to
  lt-modal-overlay/lt-modal/lt-modal-header/lt-modal-body/lt-modal-footer
- Replace style="display:none" with aria-hidden="true" on all modals
- Replace modal open/close style.display with lt.modal.open/close()
- Update modal buttons to lt-btn lt-btn-primary/lt-btn-ghost classes
- Remove manual ESC keydown handlers (replaced by lt.keys.initDefaults)
- Fix unescaped timezone values in TicketView inline script
