fix(dashboard): Change horizontal filter bar divider truncation logic

[codyml]

SUMMARY

Currently, non-overflowed horizontal native filter dividers follow the following truncation logic:

• If the divider title is truncated or there is a divider description set or both, the description icon is visible
• Hovering over the description icon will show one or both of the following:
  • The full title in bold, if the title is truncated
  • The description if present

This PR modifies that behavior to the following:

• If the divider title is truncated, hovering over the title will show the full title in standard font weight
• If and only if there is a divider description set, the description icon will be visible and hovering over it will show the full description
