AttachmentModel::getAttachments() had no LIMIT/OFFSET, so a ticket
with hundreds of attachments loaded and rendered every one of them in
a single API response and DOM grid, unbounded.
Added optional limit/offset to getAttachments(), matching the pattern
already used by CommentModel::getCommentsByTicketId(). The GET handler
in upload_attachment.php now accepts limit/offset (default 40, capped
at 100) and returns total/has_more alongside the page of attachments.
ticket.js's loadAttachments()/renderAttachments() now fetch and append
pages, showing a "Load more attachments (N remaining)" control when
more are available. Verified against real MariaDB with 12 attachments
across 3 pages of 5: no duplicates or gaps across pages, and the
legacy unlimited call (getAttachments($ticketId) with no
limit/offset) still returns everything unchanged.

All ticket_id parameters were bound as integer ("i"), which stripped
leading zeros before insertion into ticket_attachments.ticket_id
(VARCHAR 9). This caused a mismatch: upload_attachment.php creates
the directory using the full string (e.g. /uploads/000123456/) but
the DB stored the integer form ("123456"), so download and delete
would look in the wrong path.
Changed getAttachments, addAttachment, getTotalSizeForTicket, and
getAttachmentCount to use string binding ("s") so the canonical
zero-padded ticket ID is stored and read back consistently.

- bulk_operation.php: replace is_numeric() with strict int cast+equality to reject scientific notation
- AttachmentModel.php: fix bind_param type strings (s→i for integer ticket IDs)
- CommentModel.php: use strict !== comparison with (int) cast for user_id ownership checks
- ticket.js: replace all non-TDS class names (text-amber→lt-text-amber, btn→lt-btn variants, etc.)
