- Make discharge field optional in data validator
- Remove discharge from required fields list
- Add explicit null check for discharge before float conversion
- Prevent "float() argument must be a string or a real number, not 'NoneType'" errors
- Allow records with valid water levels but malformed/null discharge data
This completes the malformed data handling fix by updating the validator
to match the parser's new behavior of allowing null discharge values.
Before: Validator rejected records with null discharge
After: Validator accepts records with null discharge, validates only if present

- Change data parsing logic to make discharge data optional
- Water level data is now saved even when discharge values are malformed (e.g., "***")
- Handle malformed discharge values gracefully with null instead of skipping entire record
- Add specific handling for "***" discharge values from API
- Improve data completeness by not discarding valid water level measurements
Before: Entire station record was skipped if discharge was malformed
After: Water level data is preserved, discharge set to null for malformed values
Example fix:
- wlvalues8: 1.6 (valid) + qvalues8: "***" (malformed)
- Before: No record saved
- After: Record saved with water_level=1.6, discharge=null

- Add intelligent date selection based on current time
- Before 01:00: fetch yesterday's data only (API not updated yet)
- After 01:00: try today's data first, fallback to yesterday if needed
- Improve data availability by adapting to API update patterns
- Add comprehensive logging for date selection decisions
This ensures optimal data fetching regardless of the time of day:
- Early morning (00:00-00:59): fetches yesterday (reliable)
- Rest of day (01:00-23:59): tries today first, falls back to yesterday

- Replace fixed hourly schedule with adaptive scheduling system
- Switch to 1-minute retries when no data is available from API
- Return to hourly schedule once data is successfully fetched
- Fix data fetching to use yesterday's date (API has 1-day delay)
- Add comprehensive logging for scheduler mode changes
- Improve resilience against API data availability issues
The scheduler now intelligently adapts to data availability:
- Normal mode: hourly runs at top of each hour
- Retry mode: minute-based retries until data is available
- Automatic mode switching based on fetch success/failure
