fix: unify state logic, fix lost/travelling zones, accept both spellings

[genebean]

I really like this card but the bugs were bothering me so I got Claude Code to help me make things better. This is the second of a set of 3 PRs that when combined are what I am now using at home. The first one is #40

• Make getWizardState() the single source of truth: it now accepts a full wizard config object so it can check proximity_sensor; set hass populates a _wizardStates cache and drawTime reads from it instead of reimplementing state logic independently (which caused divergence and broke permanent locations)
• Remove pre-adding of lost/travelling zones: they now only appear on the dial when a wizard is actually in that state
• Remove the && this.config.travelling gate on travelling detection: moving by velocity or proximity sensor triggers Travelling regardless of whether the custom text key is set
• Proximity sensor check moved into getWizardState so both zone-building (set hass) and hand-positioning (drawTime) use the same decision
• Accept both 'travelling' and 'traveling' (American spelling) in config
• Accept both 'fontName' and 'fontname' spellings in config
• Default lostState to "Lost", travellingState to "Travelling" (was "Away")
• Reduce wizardOffset spread factor from 0.6 to 0.3 so hands center more accurately on their zone label
