Serial number on the player detail page

Surface the full device serial number as a copyable field on the player detail page

Problem. The player detail page shows Provision Code and Player Name but never the serial number as a labeled, copyable field. On BrightSign the provision code is the serial plus a two-character suffix, and the Player Name carries the serial with the delimiters stripped. So the data is on the page twice and usable neither time.

Example from the customer tenant: Provision Code USF52N-002740-8S, Player Name BrightSign-USF52N002740, actual serial USF52N002740.

Impact. Every BrightSign fleet workflow keys off the serial: cross-referencing BSN Cloud, opening BrightSign support tickets, RMAs, asset inventory reconciliation. The customer's current workaround is copying the last six digits and using them as a search string.

Requested change. Display the full serial as a labeled field on the player detail page with copy to clipboard. Include it in the provisioning export if it isn't already.
