Add activity-updating and -deleting capabilities

[aaron-schroeder]

Currently, once you've saved an activity, you cannot delete or modify it.

Old notes, likely irrelevant

Enhance the saved activity dashboard so it provides the option to update or modify the data if the user is logged in.

Activity fields that definitely want to be updated:

• intensity_factor
• tss
• (not a model field yet) ngp
• (not a model field yet) cp or ftp
  Activity fields that may want to be updated:
• distance_m
  • strava_json['distance']
  • Total: df['distance'].iloc[-1] - df['distance'].iloc[0]
  • distance_m(df['distance'], df['moving'])
• elevation_m
  • strava_json['total_elevation_gain']
  • df['elevation'] (naive)
  • df['elevation'] (__ m threshold)
  • df['elevation'] (naive on a profile smoothed with params {...})
• moving_time_s
  • strava_json['moving_time']
  • moving_time_s(df['time'], df['moving'])
• elapsed_time_s
  • strava_json['elapsed_time']
  • df['time'].iloc[-1] - df['time'].iloc[0]
  • Should be equivalent or within 1 second.
• created
• (not a model field yet) moving_speed_ms
  • strava_json['average_speed']
  • Combination of distance_m and moving_time_s
• (not a model field yet) average_grade_decimal
  • Combination of elevation_m and distance_m
    Activity fields that come straight from strava api:
• title
• description
• recorded
• tz_local
• strava_id
