feat: add new operational authority group

[lumtis]

Description

• Add a operational authority group for operational purpose (non-sensitive network param changes)
• Move all the admin messages to operational messages except the following which are sensitive as discussed in the doc:
  • MsgUpdateTssAddress
  • MsgUpdateContractBytecode
  • MsgUpdateSystemContract
  • MsgMigrateTssFunds

Change the migration script to set the current group 2 address to group admin and operational at the same time. The operational address should be changed with a gov prop later (with less required signatures)

Closes: #1715

!!!WARNING!!!
nosec detected in the following files: x/observer/keeper/msg_server_update_observer_test.go

Be very careful about using #nosec in code. It can be a quick way to suppress security warnings and move forward with development, it should be employed with caution. Suppressing warnings with #nosec can hide potentially serious vulnerabilities. Only use #nosec when you're absolutely certain that the security issue is either a false positive or has been mitigated in another way.

Only suppress a single rule (or a specific set of rules) within a section of code, while continuing to scan for other problems. To do this, you can list the rule(s) to be suppressed within the #nosec annotation, e.g: /* #nosec G401 */ or //#nosec G201 G202 G203
Broad #nosec annotations should be avoided, as they can hide other vulnerabilities. The CI will block you from merging this PR until you remove #nosec annotations that do not target specific rules.

Pay extra attention to the way #nosec is being used in the files listed above.
