feat(dives)!: the profile chart on a millisecond axis, readouts and salinity per recording, and the widened agency list

[aleskiontherun]

The web catches up with the API's DiveJSON changes. The profile chart reads times, duration and event time as milliseconds from the recording's own start, so a Suunto app export's first sample draws at the sub-second offset it states; every gap, tolerance and tick helper in lib/dive-profile.ts works in that unit, and seconds appear only where a person reads them (formatElapsed, formatElapsedSpoken), while ndl/tts values stay seconds. CNS, OTU and surface pressure leave Dive for Recording along with the new salinity setting: the exposure card shows the primary recording's readouts, the recordings card shows each recording's with its salinity (Fresh, EN13319, Salt), and WATER_TYPES drops en13319, so a parsed file no longer fills the dive's water type. The certification agency list gains the format's twenty new agencies, the eight notes caps become one 100,000-character notesField(), and read_as_written joins the import note codes as information.

Verified with npm run test:coverage, npm run lint, npx tsc --noEmit --strict, npm run format:check and npm run build, checked against the API's schemas at opendiving-api fb9b033.
