[Strategy Card] Truncate number to 6 decimal if range < 1

[GrandSchtroumpf]

fix #1273

When order range delta is < 1 we truncate number after 6 decimals.

Test cases :

• Create a disposable range strategy with theses prices
• Hover graph in strategy card to see prices (price is after sdk approximation)

Both below 0:

• Form: min 0.000000001 & max 0.01
• Card: min 0.0₈99999 & max 0.009999

Above & below 0:

• Form: min 0.99999 & max 1.00001
• Card: min 0.999989 & max 1.000009

Both above 0:

• Form: min 10.0005 & max 11.0000001
• Card: min 10.000499 & max 11.00
