[WIP] Fix placeholder redirection for player statistics

[Copilot]

Fix Placeholder Parsing for Player Names with Underscores

The current implementation breaks when player names contain underscores (e.g., ItzFabbb___). This PR implements the requested solution:

Changes completed:

• Update PlaceholderHook.java to support new placeholder format
  • Add support for %norder_player_<type>% (uses the player context from PlaceholderAPI)
  • Add support for %norder_player_{player_name}_<type>% (looks up specific player by name)
  • Fix parsing logic to handle player names with underscores correctly
• Update README.md to document the new placeholder formats
• Test the parsing logic to ensure it works correctly

Technical solution:

• For %norder_player_<type>%: Uses the player parameter passed by PlaceholderAPI
• For %norder_player_{player_name}_<type>%: Extracts player name by identifying the field name (last part) and reconstructing the player name from all middle parts joined with underscores
• This allows player names to contain any number of underscores without breaking the parsing

Test results:

✓ Simple placeholders work: %norder_player_totalOrders%
✓ Player names without underscores work: %norder_player_NotPatch_totalOrders%
✓ Player names with trailing underscores work: %norder_player_ItzFabbb____totalOrders%
✓ Player names with underscores in multiple positions work: %norder_player_Test_User_123__totalEarnings%

%norder_player_<>
%norder_playertotalOrders%
%norder_playertotalEarnings%
%norder_playertotalDelivered%
%norder_player_totalCollected%

I Think these placeholder needs to be re-directed to 
%norder_player_<>% instead of using "`%norder_player_<another_player>_<type>%`"

then if so we want to look the other player's statistics,
we can do

%norder_player_{player_name}<>
%norder_player{player_name}totalOrders%
%norder_player{player_name}totalEarnings%
%norder_player{player_name}totalDelivered%
%norder_player{player_name}_totalCollected%

As of right now i find that these placeholders is kinda have no purpose whatsoever, because minecraft ign also can be something like this
