The answer to the headline question appears to be simple: no.
The British were cautious and indirect about asserting their authority inside the city, but British control of the surrounding area ensured that the Chinese authorities had no way of re-establishing a presence once they were evicted. For several decades after the British evicted the Chinese authorities, the population inside the city was quite small, but by the 1920s significant numbers of squatters did start to move in. The KMT government then began to vigorously petition for authority in the 1930s and 1940s, and at times the post-war Communist did as well, but to no avail.
At some point I may try to come back and answer the sub-questions about how daily life in the city was managed, but what is clear is that Beijing (and certainly Taipei!) had nothing to do with it.
