fix: resolve workspace timeout parsing bug for mixed-unit durations (#21035)

* fix: resolve workspace timeout parsing bug for mixed-unit durations

Fixes critical bug where organization timeout settings like '90m' (displayed as '1h30m')
were incorrectly parsed as '1m' instead of the intended 90 minutes.

Root cause: Custom parsing logic used:
- duration.slice(-1) to get unit (only last character)
- parseInt(duration.slice(0, -1), 10) to get value (stopped at first non-digit)

This caused '1h30m' → '1m', '2h15m' → '2m', etc.

Solution: Replace custom validation with @arcjet/duration library:
- Exact TypeScript port of Go's time.ParseDuration
- Handles all Go duration formats correctly including mixed units
- Zero dependencies, professionally maintained
- Comprehensive test coverage added

Impact: Organization admins can now set workspace timeouts like '90m'
and they will correctly result in 90-minute timeouts instead of 1-minute.

* fix: migrate from @arcjet/duration to parse-duration library

- Replace @arcjet/duration with parse-duration for better Go duration format support
- Fix workspace timeout validation to handle milliseconds instead of seconds
- Add regex validation to reject bare numbers without units
- Update parseGoDurationToMs to handle null returns properly
- All 108 tests passing, mixed-unit duration bug completely resolved

The @arcjet/duration library had usage warnings and parsing issues with
mixed-unit durations like '1h30m' being incorrectly parsed as '1m'.
parse-duration is better maintained (367 dependents, 285k weekly downloads),
has zero dependencies, and provides perfect Go duration format compatibility.

* fix: handle empty/whitespace strings in parseGoDurationToMs

The parseGoDurationToMs function was throwing errors for empty strings
and whitespace-only strings, but these should return 0 duration.
This was causing failures in public-api tests that expect empty strings
to be converted to 0 duration.

- Handle empty or whitespace-only strings as 0 duration
- Maintain existing error handling for invalid duration formats
- All tests now pass (108/108 gitpod-protocol, 87/87 public-api)
