Adds a Metric / Imperial setting so distance, pace and weight can show as mi, min/mi and lb.

• Metric by default; imperial is opt-in under Settings → Units, stored per browser.
• Conversions live in lib/format.ts and are used across Overview, Workouts, Workout detail, Health, Plans and Queue.
• Display only. The API, wire types and iOS app stay metric.
• Splits stay 1 km (only their pace converts), and protein stays g/kg.
• Fixes a Queue bug where a goal in miles was divided by 1,000.

Testing: frontend typecheck, lint and build pass.

@johnzanussi thanks for this, super nice addition and it didn't even cross my mind as European, haha. I'll have a look for the app as well, at one point.

One change request before I merge: I'prefer metric as the default with imperial as an opt-in. en-US is the default browser language for a lot of people outside the US so I'd rather not 'guess. What do you think? Thanks!

@aderaaij Ah yes, that make sense. I will get that change in later today.
