[Feature] Add sort capabilities to ChatFlow and AgentFlow tables

[danieldabate]

As requested by someone in Discord, this PR adds sorting capabilities to the ChatFlow and AgentFlow tables.

Description:

• TableSortLabel used for the view applied to the header row
• Allow the user to sort by Name and Last modified date, descending and ascending
• Default behavior is sorted by Last modified date descending
• When user changes the sort configuration, it is stored in local storage
• Configuration for ChatFlow and AgentFlow is independent

looks good thanks @danieldabate !

One future thought, we can perhaps refractor the local storage to be 2 main objects: chatflowStyle and agentflowStyle.
And this will contains the configuration like order: desc, orderBy: updatedDate, displayStyle: list

Sounds like a good idea! I'll make the changes whenever I have some free time.
