Sync and Extend I/O Ports Table Behavior

[lmcapacho]

This PR builds on the existing GridField infrastructure to extend its behavior and ensure consistent synchronization between the I/O table and associated input fields:

• Enabled automatic sync from the I/O table to IN, OUT, and BIDI text fields when editing any cell or pressing Enter.
• Added support for signed port names using the @ prefix.
• Added support for bus ports using [msb:lsb] syntax.
• Ignored ports marked as disabled when generating the field content.
• Implemented an onEnter callback hook to allow per-table behavior such as inserting or deleting rows.
• Prevented dialog confirmation if a table cell is being edited.
• Ensured only one empty row remains visible to simplify new port entry.
• Triggered cell selection movement after row insertion to improve input flow.
