Feat: items_with_timers/1 -> items_with_timers/2 (list_cid)

[nelsonic]

At present the route for the /lists on the #165 PR is currently:

mvp/lib/app_web/router.ex

Line 32 in 10a2a6a

resources "/lists", ListController, except: [:show]

i.e: there is no "page" to :show the list.
There is no function in the controller for displaying the list.
However we planned ahead for this when introducing lists...
The items_with_timers/1 function currently

  def items_with_timers(person_id \\ 0) do
    all_list = App.List.get_all_list_for_person(person_id)
    seq = App.List.get_list_seq(all_list)

    ...

https://github.com/dwyl/mvp/blob/b8aee0e3c29d0cb45025595131248c08fbbf6a31/lib/app/item.ex#L216C7-L218

We need to update the function to accept a list_cid as the second parameter.
and lookup the list using get_list_by_cid!/1
Then we can filter the items based on the list.seq.

Todo

• Add list_cid argument to items_with_timers/1 to make it items_with_timers/2
  • if list_cid is nil then default to the "all" list.
• Create items_with_timers/2 test with a different list_cid.
