feat(favorites): Group by stop UI part 1

[KaylaBrady]

Summary

Ticket: Group favorites by stop | Favorites View UI

What is this PR for?

• Adjusts padding on the stop icon
• Adjusts formatting of route pill w/ warning icon

Not included:

• This doesn't adjust the placement of the warning icon for branched routes; that will involve some data structure changes, so I'll look into that in a follow-up
• Outstanding question to design about whether we want to change anything to accommodate longer bus pills

iOS
- [ ] If you added any user-facing strings on iOS, are they included in Localizable.xcstrings?
- [ ] Add temporary machine translations, marked "Needs Review"

android
- [ ] All user-facing strings added to strings resource in alphabetical order
- [ ] Expensive calculations are run in withContext(Dispatchers.Default) where possible (ideally in shared code)

Testing

What testing have you done?

• Ran locally in iOS & android

platform	group by stop	group by route

nitpick: It would reduce the code a bit to have this on a constant and put it here and on the else block

[KaylaBrady]

I'll address this in the follow-up PR where I need to make this section a bit more reusable anyway!

Actually ended up including in this one

Now favorites will be group by stop, are we planning to give the pill and text the same padding space so they look more align with each other?

[KaylaBrady]

Note: This "GL B" rounded fixed-width pill was never actually used anywhere because we'd instead use the "GL" fixed-width line pill representing the whole line instead of just one GL route.

With these changes, the unused "GL B" rounded fixed-width pill is effectively replaced by the "B" circle pill.

@thedecaftony yes, based on this thread with design! I just pushed a change for that, would you mind re-reviewing this PR? I updated the description with images after this change.
