Name request service

[55Honey]

This is about https://github.com/chromiecraft/configuration/discussions/349

• Create a service page telling players that they unlock a name. It is not reserved once unlocked and free to use for anyone.

• Create a text field where the user can enter a name. When pressing Enter / clicking Confirm, the DB is checked for availability as follows:

• Find the account_id holding the character:

SELECT `level`,`account` FROM `characters` WHERE `name` = @name COLLATE UTF8MB4_BIN;

• Check if the account is a GM account on the main realm:

SELECT `id` FROM `account_access` WHERE `id` = @account_id AND `RealmID` < 2;

Deny the service "This name is not available for request.", if there is a result.

• Check if the account wasn't logged in for a while. (Pseudo code)

if @level < 5 then
  min_time_since_login = 30days
elseif @level < 30 then
  min_time_since_login = 90 days
elseif @level < 60 then
  min_time_since_login = 180 days
else
  min_time_since_login = 360 days
end

• Check if the account wasn't logged in for min_time_since_login by comparing it to

SELECT `username`,`last_login` FROM `account` WHERE `id` = @account_id;

If the condition is not met, deny the service. "This name is not available for request."

• Check if the account is banned currently

SELECT `unbandate` FROM `account_banned` WHERE `id` = @account_id AND `active` = 1;

If it is currently banned and the unbandate is equal to the bandate (perma ban), ask the player to submit a ticket and have us manually check if the name is appropriate to re-use.
If it is currently banned and the unbandate is in the future, tell the player to try again after the ban expires.

Otherwise confirm the service and grant it as follows:
Execute a server-side script (Core or Lua via Soap) which does the following:

• lock the account holding the name currently for 5min
• Force a free rename for the character holding the name currently
• Rename the character to a random valid string which isn't a name currently
