Minor label fixes to TimelineBarChart

[evan-schiewe]

This PR implements two small labeling fixes to the TimelineBarChart component:

1. Format the mouseover labels as "HH:MM" strings. They are currently displayed a decimals in units of hours, which is not particularly readable especially for a single day time period.
2. Fixes a small bug in the X-axis label generation for the month time period that generated ordinals like "21th", "22th", etc.

---

Important

Fixes mouseover label format to "HH:MM" and corrects ordinal suffixes for month day labels in TimelineBarChart.vue.

• Behavior:
  • Mouseover labels in TimelineBarChart.vue now display time as "HH:MM" instead of decimal hours.
  • Fixes ordinal suffixes for day labels in month view to correctly display "1st", "2nd", "3rd", etc.
• Functions:
  • Adds toOrdinalSuffix() function in TimelineBarChart.vue to generate correct ordinal suffixes.
  • Updates tooltip label callback in chartOptions() to format time as "HH:MM".

• Draft comment:
  Great use of Intl.PluralRules for ordinal suffixes. Consider removing or updating the FIXME comment if the month is now determined via the given timeperiod start.
• Reason this comment was not posted:
  Comment was on unchanged code.

2. src/visualizations/TimelineBarChart.vue:117

• Draft comment:
  Tooltip label formatting now converts fractional hours to HH:MM correctly. Confirm that context.parsed.y is always defined as expected.
• Reason this comment was not posted:
  Comment did not seem useful. Confidence is useful = 0% <= threshold 50% This comment is asking the PR author to confirm that a variable is always defined as expected, which falls under the rule of not asking the author to confirm their intention or ensure behavior. It doesn't provide a specific suggestion or point out a clear issue.

3. src/visualizations/TimelineBarChart.vue:80

• Draft comment:
  Ordinal generation refactor looks good, but the FIXME about using timeperiod_start to determine the month remains. Consider addressing it to ensure correct day count for non-standard month starts.
• Reason this comment was not posted:
  Comment was on unchanged code.

1. src/visualizations/TimelineBarChart.vue:76

• Draft comment:
  Good fix for month ordinal labels. Consider moving Intl.PluralRules and ordinalsEnUS outside of the computed property to avoid re-instantiation on each re-render.
• Reason this comment was not posted:
  Confidence changes required: 33% <= threshold 50% None

2. src/visualizations/TimelineBarChart.vue:116

• Draft comment:
  The tooltip callback cleanly converts fractional hours to HH:MM. Ensure rounding edge cases (e.g., minute rounding to 60) are sufficiently tested.

  Confidence changes required: 10% <= threshold 50% None

3. src/visualizations/TimelineBarChart.vue:72

• Draft comment:
  The FIXME comment about needing access to the timeperiod start for the month labels is now obsolete. Remove it if no longer needed.
• Reason this comment was not posted:
  Confidence changes required: 33% <= threshold 50% None

4. src/visualizations/TimelineBarChart.vue:116

• Draft comment:
  For strict 'HH:MM' formatting, consider zero-padding the hours as well (e.g. using padStart) so that single-digit hours appear as '01', '02', etc.
